Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979790, here are decompositions:
- 3 + 979787 = 979790
- 43 + 979747 = 979790
- 73 + 979717 = 979790
- 139 + 979651 = 979790
- 223 + 979567 = 979790
- 241 + 979549 = 979790
- 271 + 979519 = 979790
- 367 + 979423 = 979790
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 979,790 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 979790 first appears in π at position 421,215 of the decimal expansion (the 421,215ordinal-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.
