Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979290, here are decompositions:
- 7 + 979283 = 979290
- 17 + 979273 = 979290
- 29 + 979261 = 979290
- 61 + 979229 = 979290
- 71 + 979219 = 979290
- 79 + 979211 = 979290
- 83 + 979207 = 979290
- 89 + 979201 = 979290
Showing the first eight; more decompositions exist.
