Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544782, here are decompositions:
- 11 + 31544771 = 31544782
- 23 + 31544759 = 31544782
- 239 + 31544543 = 31544782
- 251 + 31544531 = 31544782
- 389 + 31544393 = 31544782
- 419 + 31544363 = 31544782
- 569 + 31544213 = 31544782
- 593 + 31544189 = 31544782
Showing the first eight; more decompositions exist.
