Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612912, here are decompositions:
- 59 + 31612853 = 31612912
- 173 + 31612739 = 31612912
- 179 + 31612733 = 31612912
- 251 + 31612661 = 31612912
- 293 + 31612619 = 31612912
- 431 + 31612481 = 31612912
- 521 + 31612391 = 31612912
- 599 + 31612313 = 31612912
Showing the first eight; more decompositions exist.
