Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990304, here are decompositions:
- 11 + 990293 = 990304
- 17 + 990287 = 990304
- 23 + 990281 = 990304
- 167 + 990137 = 990304
- 251 + 990053 = 990304
- 281 + 990023 = 990304
- 353 + 989951 = 990304
- 383 + 989921 = 990304
Showing the first eight; more decompositions exist.
