Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544578, here are decompositions:
- 5 + 31544573 = 31544578
- 17 + 31544561 = 31544578
- 47 + 31544531 = 31544578
- 281 + 31544297 = 31544578
- 389 + 31544189 = 31544578
- 479 + 31544099 = 31544578
- 521 + 31544057 = 31544578
- 557 + 31544021 = 31544578
Showing the first eight; more decompositions exist.
