Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529134, here are decompositions:
- 47 + 31529087 = 31529134
- 53 + 31529081 = 31529134
- 137 + 31528997 = 31529134
- 167 + 31528967 = 31529134
- 281 + 31528853 = 31529134
- 293 + 31528841 = 31529134
- 311 + 31528823 = 31529134
- 383 + 31528751 = 31529134
Showing the first eight; more decompositions exist.
