Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78490, here are decompositions:

3 + 78487 = 78490
11 + 78479 = 78490
23 + 78467 = 78490
53 + 78437 = 78490
89 + 78401 = 78490
149 + 78341 = 78490
173 + 78317 = 78490
179 + 78311 = 78490

Showing the first eight; more decompositions exist.
