Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79720, here are decompositions:

23 + 79697 = 79720
29 + 79691 = 79720
89 + 79631 = 79720
107 + 79613 = 79720
131 + 79589 = 79720
227 + 79493 = 79720
239 + 79481 = 79720
269 + 79451 = 79720

Showing the first eight; more decompositions exist.
