Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531426, here are decompositions:
- 5 + 31531421 = 31531426
- 23 + 31531403 = 31531426
- 263 + 31531163 = 31531426
- 347 + 31531079 = 31531426
- 449 + 31530977 = 31531426
- 467 + 31530959 = 31531426
- 593 + 31530833 = 31531426
- 599 + 31530827 = 31531426
Showing the first eight; more decompositions exist.
