Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538804, here are decompositions:
- 61 + 31538743 = 31538804
- 151 + 31538653 = 31538804
- 163 + 31538641 = 31538804
- 181 + 31538623 = 31538804
- 223 + 31538581 = 31538804
- 277 + 31538527 = 31538804
- 313 + 31538491 = 31538804
- 331 + 31538473 = 31538804
Showing the first eight; more decompositions exist.
