Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543592, here are decompositions:
- 13 + 31543579 = 31543592
- 61 + 31543531 = 31543592
- 103 + 31543489 = 31543592
- 139 + 31543453 = 31543592
- 163 + 31543429 = 31543592
- 349 + 31543243 = 31543592
- 373 + 31543219 = 31543592
- 523 + 31543069 = 31543592
Showing the first eight; more decompositions exist.
