Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003728, here are decompositions:
- 17 + 1003711 = 1003728
- 97 + 1003631 = 1003728
- 101 + 1003627 = 1003728
- 107 + 1003621 = 1003728
- 109 + 1003619 = 1003728
- 127 + 1003601 = 1003728
- 139 + 1003589 = 1003728
- 179 + 1003549 = 1003728
Showing the first eight; more decompositions exist.
