Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538594, here are decompositions:
- 13 + 31538581 = 31538594
- 37 + 31538557 = 31538594
- 67 + 31538527 = 31538594
- 103 + 31538491 = 31538594
- 151 + 31538443 = 31538594
- 223 + 31538371 = 31538594
- 433 + 31538161 = 31538594
- 457 + 31538137 = 31538594
Showing the first eight; more decompositions exist.
