Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472068, here are decompositions:
- 101 + 31471967 = 31472068
- 167 + 31471901 = 31472068
- 269 + 31471799 = 31472068
- 281 + 31471787 = 31472068
- 401 + 31471667 = 31472068
- 431 + 31471637 = 31472068
- 491 + 31471577 = 31472068
- 557 + 31471511 = 31472068
Showing the first eight; more decompositions exist.
