Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117220, here are decompositions:
- 11 + 117209 = 117220
- 17 + 117203 = 117220
- 29 + 117191 = 117220
- 53 + 117167 = 117220
- 101 + 117119 = 117220
- 149 + 117071 = 117220
- 167 + 117053 = 117220
- 179 + 117041 = 117220
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 117,220 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 117220 first appears in π at position 622,876 of the decimal expansion (the 622,876ordinal-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.
