Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529254, here are decompositions:
- 5 + 31529249 = 31529254
- 11 + 31529243 = 31529254
- 41 + 31529213 = 31529254
- 167 + 31529087 = 31529254
- 173 + 31529081 = 31529254
- 257 + 31528997 = 31529254
- 401 + 31528853 = 31529254
- 431 + 31528823 = 31529254
Showing the first eight; more decompositions exist.
