Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90308, here are decompositions:
- 19 + 90289 = 90308
- 37 + 90271 = 90308
- 61 + 90247 = 90308
- 109 + 90199 = 90308
- 181 + 90127 = 90308
- 241 + 90067 = 90308
- 277 + 90031 = 90308
- 307 + 90001 = 90308
Showing the first eight; more decompositions exist.
