Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175388, here are decompositions:

  • 61 + 175327 = 175388
  • 79 + 175309 = 175388
  • 97 + 175291 = 175388
  • 127 + 175261 = 175388
  • 307 + 175081 = 175388
  • 349 + 175039 = 175388
  • 397 + 174991 = 175388
  • 457 + 174931 = 175388

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 175,388 and was likely granted around 1874.

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

Position in π

The digit sequence 175388 first appears in π at position 201,188 of the decimal expansion (the 201,188ordinal-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.
