Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979780, here are decompositions:
- 23 + 979757 = 979780
- 71 + 979709 = 979780
- 89 + 979691 = 979780
- 227 + 979553 = 979780
- 239 + 979541 = 979780
- 251 + 979529 = 979780
- 401 + 979379 = 979780
- 419 + 979361 = 979780
Showing the first eight; more decompositions exist.
