Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528266, here are decompositions:
- 37 + 31528229 = 31528266
- 53 + 31528213 = 31528266
- 59 + 31528207 = 31528266
- 97 + 31528169 = 31528266
- 109 + 31528157 = 31528266
- 139 + 31528127 = 31528266
- 163 + 31528103 = 31528266
- 173 + 31528093 = 31528266
Showing the first eight; more decompositions exist.
