Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529106, here are decompositions:
- 17 + 31529089 = 31529106
- 19 + 31529087 = 31529106
- 53 + 31529053 = 31529106
- 109 + 31528997 = 31529106
- 113 + 31528993 = 31529106
- 137 + 31528969 = 31529106
- 139 + 31528967 = 31529106
- 197 + 31528909 = 31529106
Showing the first eight; more decompositions exist.
