Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538346, here are decompositions:
- 13 + 31538333 = 31538346
- 17 + 31538329 = 31538346
- 19 + 31538327 = 31538346
- 107 + 31538239 = 31538346
- 139 + 31538207 = 31538346
- 193 + 31538153 = 31538346
- 233 + 31538113 = 31538346
- 239 + 31538107 = 31538346
Showing the first eight; more decompositions exist.
