Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90512, here are decompositions:
- 13 + 90499 = 90512
- 31 + 90481 = 90512
- 43 + 90469 = 90512
- 73 + 90439 = 90512
- 109 + 90403 = 90512
- 139 + 90373 = 90512
- 199 + 90313 = 90512
- 223 + 90289 = 90512
Showing the first eight; more decompositions exist.
