Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588318, here are decompositions:
- 5 + 31588313 = 31588318
- 11 + 31588307 = 31588318
- 71 + 31588247 = 31588318
- 257 + 31588061 = 31588318
- 569 + 31587749 = 31588318
- 617 + 31587701 = 31588318
- 659 + 31587659 = 31588318
- 701 + 31587617 = 31588318
Showing the first eight; more decompositions exist.
