Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90688, here are decompositions:
- 11 + 90677 = 90688
- 29 + 90659 = 90688
- 41 + 90647 = 90688
- 47 + 90641 = 90688
- 71 + 90617 = 90688
- 89 + 90599 = 90688
- 251 + 90437 = 90688
- 281 + 90407 = 90688
Showing the first eight; more decompositions exist.
