Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531626, here are decompositions:
- 47 + 31531579 = 31531626
- 103 + 31531523 = 31531626
- 173 + 31531453 = 31531626
- 223 + 31531403 = 31531626
- 227 + 31531399 = 31531626
- 257 + 31531369 = 31531626
- 353 + 31531273 = 31531626
- 359 + 31531267 = 31531626
Showing the first eight; more decompositions exist.
