Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507354, here are decompositions:
- 3 + 31507351 = 31507354
- 71 + 31507283 = 31507354
- 83 + 31507271 = 31507354
- 173 + 31507181 = 31507354
- 317 + 31507037 = 31507354
- 443 + 31506911 = 31507354
- 467 + 31506887 = 31507354
- 563 + 31506791 = 31507354
Showing the first eight; more decompositions exist.
