Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90660, here are decompositions:
- 13 + 90647 = 90660
- 19 + 90641 = 90660
- 29 + 90631 = 90660
- 41 + 90619 = 90660
- 43 + 90617 = 90660
- 61 + 90599 = 90660
- 113 + 90547 = 90660
- 127 + 90533 = 90660
Showing the first eight; more decompositions exist.
