Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507426, here are decompositions:
- 23 + 31507403 = 31507426
- 59 + 31507367 = 31507426
- 107 + 31507319 = 31507426
- 227 + 31507199 = 31507426
- 317 + 31507109 = 31507426
- 389 + 31507037 = 31507426
- 449 + 31506977 = 31507426
- 617 + 31506809 = 31507426
Showing the first eight; more decompositions exist.
