Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544340, here are decompositions:
- 17 + 31544323 = 31544340
- 29 + 31544311 = 31544340
- 43 + 31544297 = 31544340
- 59 + 31544281 = 31544340
- 127 + 31544213 = 31544340
- 151 + 31544189 = 31544340
- 173 + 31544167 = 31544340
- 241 + 31544099 = 31544340
Showing the first eight; more decompositions exist.
