Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543526, here are decompositions:
- 37 + 31543489 = 31543526
- 73 + 31543453 = 31543526
- 97 + 31543429 = 31543526
- 283 + 31543243 = 31543526
- 307 + 31543219 = 31543526
- 457 + 31543069 = 31543526
- 577 + 31542949 = 31543526
- 727 + 31542799 = 31543526
Showing the first eight; more decompositions exist.
