Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979842, here are decompositions:
- 11 + 979831 = 979842
- 23 + 979819 = 979842
- 151 + 979691 = 979842
- 191 + 979651 = 979842
- 293 + 979549 = 979842
- 313 + 979529 = 979842
- 419 + 979423 = 979842
- 439 + 979403 = 979842
Showing the first eight; more decompositions exist.
