Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78822, here are decompositions:

13 + 78809 = 78822
19 + 78803 = 78822
31 + 78791 = 78822
41 + 78781 = 78822
43 + 78779 = 78822
101 + 78721 = 78822
109 + 78713 = 78822
131 + 78691 = 78822

Showing the first eight; more decompositions exist.
