Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78730, here are decompositions:

17 + 78713 = 78730
23 + 78707 = 78730
107 + 78623 = 78730
137 + 78593 = 78730
191 + 78539 = 78730
233 + 78497 = 78730
251 + 78479 = 78730
263 + 78467 = 78730

Showing the first eight; more decompositions exist.
