Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531896, here are decompositions:
- 13 + 31531883 = 31531896
- 79 + 31531817 = 31531896
- 83 + 31531813 = 31531896
- 229 + 31531667 = 31531896
- 257 + 31531639 = 31531896
- 269 + 31531627 = 31531896
- 317 + 31531579 = 31531896
- 373 + 31531523 = 31531896
Showing the first eight; more decompositions exist.
