Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618508, here are decompositions:
- 67 + 31618441 = 31618508
- 211 + 31618297 = 31618508
- 277 + 31618231 = 31618508
- 409 + 31618099 = 31618508
- 541 + 31617967 = 31618508
- 547 + 31617961 = 31618508
- 619 + 31617889 = 31618508
- 631 + 31617877 = 31618508
Showing the first eight; more decompositions exist.
