Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 107820, here are decompositions:
- 29 + 107791 = 107820
- 43 + 107777 = 107820
- 47 + 107773 = 107820
- 59 + 107761 = 107820
- 73 + 107747 = 107820
- 79 + 107741 = 107820
- 101 + 107719 = 107820
- 103 + 107717 = 107820
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 107,820 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 107820 first appears in π at position 858,720 of the decimal expansion (the 858,720ordinal-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.
