Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501120, here are decompositions:
- 17 + 501103 = 501120
- 31 + 501089 = 501120
- 43 + 501077 = 501120
- 83 + 501037 = 501120
- 89 + 501031 = 501120
- 101 + 501019 = 501120
- 107 + 501013 = 501120
- 163 + 500957 = 501120
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 501,120 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 501120 first appears in π at position 71,106 of the decimal expansion (the 71,106ordinal-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.
