Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90242, here are decompositions:
- 3 + 90239 = 90242
- 43 + 90199 = 90242
- 79 + 90163 = 90242
- 211 + 90031 = 90242
- 223 + 90019 = 90242
- 241 + 90001 = 90242
- 283 + 89959 = 90242
- 409 + 89833 = 90242
Showing the first eight; more decompositions exist.
