Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531594, here are decompositions:
- 71 + 31531523 = 31531594
- 137 + 31531457 = 31531594
- 173 + 31531421 = 31531594
- 191 + 31531403 = 31531594
- 293 + 31531301 = 31531594
- 431 + 31531163 = 31531594
- 593 + 31531001 = 31531594
- 617 + 31530977 = 31531594
Showing the first eight; more decompositions exist.
