Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78508, here are decompositions:

11 + 78497 = 78508
29 + 78479 = 78508
41 + 78467 = 78508
71 + 78437 = 78508
107 + 78401 = 78508
167 + 78341 = 78508
191 + 78317 = 78508
197 + 78311 = 78508

Showing the first eight; more decompositions exist.
