Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545554, here are decompositions:
- 67 + 31545487 = 31545554
- 163 + 31545391 = 31545554
- 181 + 31545373 = 31545554
- 211 + 31545343 = 31545554
- 223 + 31545331 = 31545554
- 373 + 31545181 = 31545554
- 457 + 31545097 = 31545554
- 463 + 31545091 = 31545554
Showing the first eight; more decompositions exist.
