Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526712, here are decompositions:
- 23 + 31526689 = 31526712
- 43 + 31526669 = 31526712
- 79 + 31526633 = 31526712
- 109 + 31526603 = 31526712
- 149 + 31526563 = 31526712
- 179 + 31526533 = 31526712
- 223 + 31526489 = 31526712
- 281 + 31526431 = 31526712
Showing the first eight; more decompositions exist.
