Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538648, here are decompositions:

  • 59 + 538589 = 538648
  • 137 + 538511 = 538648
  • 167 + 538481 = 538648
  • 191 + 538457 = 538648
  • 251 + 538397 = 538648
  • 281 + 538367 = 538648
  • 317 + 538331 = 538648
  • 347 + 538301 = 538648

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 538,648 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 538648 first appears in π at position 529,740 of the decimal expansion (the 529,740ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
