Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117920, here are decompositions:
- 3 + 117917 = 117920
- 31 + 117889 = 117920
- 37 + 117883 = 117920
- 43 + 117877 = 117920
- 79 + 117841 = 117920
- 109 + 117811 = 117920
- 157 + 117763 = 117920
- 163 + 117757 = 117920
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 117,920 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 117920 first appears in π at position 35,780 of the decimal expansion (the 35,780ordinal-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.
