Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78818, here are decompositions:

31 + 78787 = 78818
37 + 78781 = 78818
97 + 78721 = 78818
127 + 78691 = 78818
211 + 78607 = 78818
241 + 78577 = 78818
277 + 78541 = 78818
307 + 78511 = 78818

Showing the first eight; more decompositions exist.
