Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998458, here are decompositions:

  • 29 + 998429 = 998458
  • 47 + 998411 = 998458
  • 59 + 998399 = 998458
  • 239 + 998219 = 998458
  • 257 + 998201 = 998458
  • 311 + 998147 = 998458
  • 347 + 998111 = 998458
  • 389 + 998069 = 998458

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 998,458 and was likely granted around 1911.

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

Position in π

The digit sequence 998458 first appears in π at position 252,789 of the decimal expansion (the 252,789ordinal-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.
