Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79778, here are decompositions:

79 + 79699 = 79778
109 + 79669 = 79778
151 + 79627 = 79778
157 + 79621 = 79778
199 + 79579 = 79778
229 + 79549 = 79778
241 + 79537 = 79778
367 + 79411 = 79778

Showing the first eight; more decompositions exist.
