Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78550, here are decompositions:

11 + 78539 = 78550
41 + 78509 = 78550
53 + 78497 = 78550
71 + 78479 = 78550
83 + 78467 = 78550
113 + 78437 = 78550
149 + 78401 = 78550
233 + 78317 = 78550

Showing the first eight; more decompositions exist.
