Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78520, here are decompositions:

3 + 78517 = 78520
11 + 78509 = 78520
23 + 78497 = 78520
41 + 78479 = 78520
53 + 78467 = 78520
83 + 78437 = 78520
173 + 78347 = 78520
179 + 78341 = 78520

Showing the first eight; more decompositions exist.
