Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529104, here are decompositions:
- 17 + 31529087 = 31529104
- 23 + 31529081 = 31529104
- 107 + 31528997 = 31529104
- 137 + 31528967 = 31529104
- 251 + 31528853 = 31529104
- 263 + 31528841 = 31529104
- 281 + 31528823 = 31529104
- 293 + 31528811 = 31529104
Showing the first eight; more decompositions exist.
