Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532008, here are decompositions:
- 5 + 31532003 = 31532008
- 41 + 31531967 = 31532008
- 191 + 31531817 = 31532008
- 257 + 31531751 = 31532008
- 281 + 31531727 = 31532008
- 359 + 31531649 = 31532008
- 587 + 31531421 = 31532008
- 929 + 31531079 = 31532008
Showing the first eight; more decompositions exist.
