Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90918, here are decompositions:
- 7 + 90911 = 90918
- 11 + 90907 = 90918
- 17 + 90901 = 90918
- 31 + 90887 = 90918
- 71 + 90847 = 90918
- 97 + 90821 = 90918
- 131 + 90787 = 90918
- 239 + 90679 = 90918
Showing the first eight; more decompositions exist.
