Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78516, here are decompositions:

5 + 78511 = 78516
7 + 78509 = 78516
19 + 78497 = 78516
29 + 78487 = 78516
37 + 78479 = 78516
79 + 78437 = 78516
89 + 78427 = 78516
149 + 78367 = 78516

Showing the first eight; more decompositions exist.
