Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90240, here are decompositions:
- 13 + 90227 = 90240
- 23 + 90217 = 90240
- 37 + 90203 = 90240
- 41 + 90199 = 90240
- 43 + 90197 = 90240
- 53 + 90187 = 90240
- 67 + 90173 = 90240
- 113 + 90127 = 90240
Showing the first eight; more decompositions exist.
