Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117640, here are decompositions:
- 23 + 117617 = 117640
- 101 + 117539 = 117640
- 137 + 117503 = 117640
- 197 + 117443 = 117640
- 227 + 117413 = 117640
- 251 + 117389 = 117640
- 269 + 117371 = 117640
- 311 + 117329 = 117640
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 117,640 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 117640 first appears in π at position 783,446 of the decimal expansion (the 783,446ordinal-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.
