Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79420, here are decompositions:
- 23 + 79397 = 79420
- 41 + 79379 = 79420
- 53 + 79367 = 79420
- 71 + 79349 = 79420
- 83 + 79337 = 79420
- 101 + 79319 = 79420
- 137 + 79283 = 79420
- 179 + 79241 = 79420
Showing the first eight; more decompositions exist.
