Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544238, here are decompositions:
- 17 + 31544221 = 31544238
- 31 + 31544207 = 31544238
- 59 + 31544179 = 31544238
- 67 + 31544171 = 31544238
- 71 + 31544167 = 31544238
- 107 + 31544131 = 31544238
- 139 + 31544099 = 31544238
- 149 + 31544089 = 31544238
Showing the first eight; more decompositions exist.
