Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78510, here are decompositions:

13 + 78497 = 78510
23 + 78487 = 78510
31 + 78479 = 78510
43 + 78467 = 78510
71 + 78439 = 78510
73 + 78437 = 78510
83 + 78427 = 78510
109 + 78401 = 78510

Showing the first eight; more decompositions exist.
