Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525772, here are decompositions:
- 73 + 31525699 = 31525772
- 163 + 31525609 = 31525772
- 283 + 31525489 = 31525772
- 571 + 31525201 = 31525772
- 1009 + 31524763 = 31525772
- 1051 + 31524721 = 31525772
- 1129 + 31524643 = 31525772
- 1231 + 31524541 = 31525772
Showing the first eight; more decompositions exist.
