Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78538, here are decompositions:

29 + 78509 = 78538
41 + 78497 = 78538
59 + 78479 = 78538
71 + 78467 = 78538
101 + 78437 = 78538
137 + 78401 = 78538
191 + 78347 = 78538
197 + 78341 = 78538

Showing the first eight; more decompositions exist.
