Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538336, here are decompositions:
- 3 + 31538333 = 31538336
- 7 + 31538329 = 31538336
- 97 + 31538239 = 31538336
- 199 + 31538137 = 31538336
- 223 + 31538113 = 31538336
- 229 + 31538107 = 31538336
- 283 + 31538053 = 31538336
- 307 + 31538029 = 31538336
Showing the first eight; more decompositions exist.
