Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979742, here are decompositions:
- 193 + 979549 = 979742
- 199 + 979543 = 979742
- 223 + 979519 = 979742
- 271 + 979471 = 979742
- 373 + 979369 = 979742
- 409 + 979333 = 979742
- 523 + 979219 = 979742
- 541 + 979201 = 979742
Showing the first eight; more decompositions exist.
