Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544644, here are decompositions:
- 71 + 31544573 = 31544644
- 83 + 31544561 = 31544644
- 101 + 31544543 = 31544644
- 113 + 31544531 = 31544644
- 227 + 31544417 = 31544644
- 251 + 31544393 = 31544644
- 281 + 31544363 = 31544644
- 347 + 31544297 = 31544644
Showing the first eight; more decompositions exist.
