Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474316, here are decompositions:
- 67 + 31474249 = 31474316
- 103 + 31474213 = 31474316
- 283 + 31474033 = 31474316
- 409 + 31473907 = 31474316
- 613 + 31473703 = 31474316
- 733 + 31473583 = 31474316
- 787 + 31473529 = 31474316
- 829 + 31473487 = 31474316
Showing the first eight; more decompositions exist.
