Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538526, here are decompositions:
- 23 + 31538503 = 31538526
- 37 + 31538489 = 31538526
- 53 + 31538473 = 31538526
- 83 + 31538443 = 31538526
- 193 + 31538333 = 31538526
- 197 + 31538329 = 31538526
- 199 + 31538327 = 31538526
- 373 + 31538153 = 31538526
Showing the first eight; more decompositions exist.
