Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544748, here are decompositions:
- 29 + 31544719 = 31544748
- 31 + 31544717 = 31544748
- 197 + 31544551 = 31544748
- 239 + 31544509 = 31544748
- 331 + 31544417 = 31544748
- 401 + 31544347 = 31544748
- 467 + 31544281 = 31544748
- 541 + 31544207 = 31544748
Showing the first eight; more decompositions exist.
