Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78778, here are decompositions:

41 + 78737 = 78778
71 + 78707 = 78778
239 + 78539 = 78778
269 + 78509 = 78778
281 + 78497 = 78778
311 + 78467 = 78778
431 + 78347 = 78778
461 + 78317 = 78778

Showing the first eight; more decompositions exist.
