Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544752, here are decompositions:
- 3 + 31544749 = 31544752
- 179 + 31544573 = 31544752
- 191 + 31544561 = 31544752
- 359 + 31544393 = 31544752
- 389 + 31544363 = 31544752
- 563 + 31544189 = 31544752
- 599 + 31544153 = 31544752
- 653 + 31544099 = 31544752
Showing the first eight; more decompositions exist.
