Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990670, here are decompositions:
- 71 + 990599 = 990670
- 167 + 990503 = 990670
- 173 + 990497 = 990670
- 281 + 990389 = 990670
- 293 + 990377 = 990670
- 311 + 990359 = 990670
- 347 + 990323 = 990670
- 383 + 990287 = 990670
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 990,670 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 990670 first appears in π at position 972,825 of the decimal expansion (the 972,825ordinal-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.
