Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528528, here are decompositions:
- 17 + 528511 = 528528
- 19 + 528509 = 528528
- 37 + 528491 = 528528
- 41 + 528487 = 528528
- 59 + 528469 = 528528
- 109 + 528419 = 528528
- 127 + 528401 = 528528
- 137 + 528391 = 528528
Showing the first eight; more decompositions exist.
