Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90066, here are decompositions:
- 7 + 90059 = 90066
- 13 + 90053 = 90066
- 43 + 90023 = 90066
- 47 + 90019 = 90066
- 59 + 90007 = 90066
- 83 + 89983 = 90066
- 89 + 89977 = 90066
- 103 + 89963 = 90066
Showing the first eight; more decompositions exist.
