Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123528, here are decompositions:
- 11 + 123517 = 123528
- 29 + 123499 = 123528
- 37 + 123491 = 123528
- 71 + 123457 = 123528
- 79 + 123449 = 123528
- 89 + 123439 = 123528
- 101 + 123427 = 123528
- 109 + 123419 = 123528
Showing the first eight; more decompositions exist.
