Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492838, here are decompositions:
- 37 + 31492801 = 31492838
- 61 + 31492777 = 31492838
- 67 + 31492771 = 31492838
- 211 + 31492627 = 31492838
- 241 + 31492597 = 31492838
- 271 + 31492567 = 31492838
- 367 + 31492471 = 31492838
- 409 + 31492429 = 31492838
Showing the first eight; more decompositions exist.
