Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90102, here are decompositions:
- 13 + 90089 = 90102
- 29 + 90073 = 90102
- 31 + 90071 = 90102
- 43 + 90059 = 90102
- 71 + 90031 = 90102
- 79 + 90023 = 90102
- 83 + 90019 = 90102
- 101 + 90001 = 90102
Showing the first eight; more decompositions exist.
