Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124120, here are decompositions:
- 23 + 124097 = 124120
- 53 + 124067 = 124120
- 131 + 123989 = 124120
- 137 + 123983 = 124120
- 167 + 123953 = 124120
- 179 + 123941 = 124120
- 197 + 123923 = 124120
- 233 + 123887 = 124120
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 124,120 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 124120 first appears in π at position 8,619 of the decimal expansion (the 8,619ordinal-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.
