Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529094, here are decompositions:
- 5 + 31529089 = 31529094
- 7 + 31529087 = 31529094
- 13 + 31529081 = 31529094
- 41 + 31529053 = 31529094
- 97 + 31528997 = 31529094
- 101 + 31528993 = 31529094
- 127 + 31528967 = 31529094
- 241 + 31528853 = 31529094
Showing the first eight; more decompositions exist.
