Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78688, here are decompositions:

149 + 78539 = 78688
179 + 78509 = 78688
191 + 78497 = 78688
251 + 78437 = 78688
347 + 78341 = 78688
509 + 78179 = 78688
521 + 78167 = 78688
587 + 78101 = 78688

Showing the first eight; more decompositions exist.
