Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90090, here are decompositions:
- 17 + 90073 = 90090
- 19 + 90071 = 90090
- 23 + 90067 = 90090
- 31 + 90059 = 90090
- 37 + 90053 = 90090
- 59 + 90031 = 90090
- 67 + 90023 = 90090
- 71 + 90019 = 90090
Showing the first eight; more decompositions exist.
