Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122798, here are decompositions:
- 37 + 122761 = 122798
- 79 + 122719 = 122798
- 97 + 122701 = 122798
- 199 + 122599 = 122798
- 241 + 122557 = 122798
- 271 + 122527 = 122798
- 349 + 122449 = 122798
- 397 + 122401 = 122798
Showing the first eight; more decompositions exist.
