Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979728, here are decompositions:
- 11 + 979717 = 979728
- 19 + 979709 = 979728
- 37 + 979691 = 979728
- 179 + 979549 = 979728
- 199 + 979529 = 979728
- 257 + 979471 = 979728
- 271 + 979457 = 979728
- 349 + 979379 = 979728
Showing the first eight; more decompositions exist.
