Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78644, here are decompositions:

37 + 78607 = 78644
61 + 78583 = 78644
67 + 78577 = 78644
73 + 78571 = 78644
103 + 78541 = 78644
127 + 78517 = 78644
157 + 78487 = 78644
277 + 78367 = 78644

Showing the first eight; more decompositions exist.
