Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979440, here are decompositions:
- 17 + 979423 = 979440
- 37 + 979403 = 979440
- 61 + 979379 = 979440
- 67 + 979373 = 979440
- 71 + 979369 = 979440
- 79 + 979361 = 979440
- 97 + 979343 = 979440
- 103 + 979337 = 979440
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 979,440 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
