Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531652, here are decompositions:
- 3 + 31531649 = 31531652
- 13 + 31531639 = 31531652
- 73 + 31531579 = 31531652
- 181 + 31531471 = 31531652
- 199 + 31531453 = 31531652
- 283 + 31531369 = 31531652
- 349 + 31531303 = 31531652
- 379 + 31531273 = 31531652
Showing the first eight; more decompositions exist.
