Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544442, here are decompositions:
- 71 + 31544371 = 31544442
- 79 + 31544363 = 31544442
- 131 + 31544311 = 31544442
- 229 + 31544213 = 31544442
- 263 + 31544179 = 31544442
- 271 + 31544171 = 31544442
- 311 + 31544131 = 31544442
- 353 + 31544089 = 31544442
Showing the first eight; more decompositions exist.
