Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529070, here are decompositions:
- 17 + 31529053 = 31529070
- 73 + 31528997 = 31529070
- 101 + 31528969 = 31529070
- 103 + 31528967 = 31529070
- 227 + 31528843 = 31529070
- 229 + 31528841 = 31529070
- 239 + 31528831 = 31529070
- 257 + 31528813 = 31529070
Showing the first eight; more decompositions exist.
