Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979488, here are decompositions:
- 7 + 979481 = 979488
- 17 + 979471 = 979488
- 31 + 979457 = 979488
- 109 + 979379 = 979488
- 127 + 979361 = 979488
- 151 + 979337 = 979488
- 197 + 979291 = 979488
- 227 + 979261 = 979488
Showing the first eight; more decompositions exist.
