Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478426, here are decompositions:
- 37 + 31478389 = 31478426
- 103 + 31478323 = 31478426
- 139 + 31478287 = 31478426
- 337 + 31478089 = 31478426
- 349 + 31478077 = 31478426
- 409 + 31478017 = 31478426
- 433 + 31477993 = 31478426
- 457 + 31477969 = 31478426
Showing the first eight; more decompositions exist.
