Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544932, here are decompositions:
- 53 + 31544879 = 31544932
- 113 + 31544819 = 31544932
- 149 + 31544783 = 31544932
- 173 + 31544759 = 31544932
- 359 + 31544573 = 31544932
- 389 + 31544543 = 31544932
- 401 + 31544531 = 31544932
- 569 + 31544363 = 31544932
Showing the first eight; more decompositions exist.
