Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90998, here are decompositions:
- 67 + 90931 = 90998
- 97 + 90901 = 90998
- 151 + 90847 = 90998
- 157 + 90841 = 90998
- 211 + 90787 = 90998
- 367 + 90631 = 90998
- 379 + 90619 = 90998
- 487 + 90511 = 90998
Showing the first eight; more decompositions exist.
