Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78540, here are decompositions:

23 + 78517 = 78540
29 + 78511 = 78540
31 + 78509 = 78540
43 + 78497 = 78540
53 + 78487 = 78540
61 + 78479 = 78540
73 + 78467 = 78540
101 + 78439 = 78540

Showing the first eight; more decompositions exist.
