Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90506, here are decompositions:
- 7 + 90499 = 90506
- 37 + 90469 = 90506
- 67 + 90439 = 90506
- 103 + 90403 = 90506
- 109 + 90397 = 90506
- 127 + 90379 = 90506
- 193 + 90313 = 90506
- 307 + 90199 = 90506
Showing the first eight; more decompositions exist.
