Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79490, here are decompositions:
- 67 + 79423 = 79490
- 79 + 79411 = 79490
- 97 + 79393 = 79490
- 157 + 79333 = 79490
- 181 + 79309 = 79490
- 211 + 79279 = 79490
- 331 + 79159 = 79490
- 337 + 79153 = 79490
Showing the first eight; more decompositions exist.
