Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78586, here are decompositions:

3 + 78583 = 78586
17 + 78569 = 78586
47 + 78539 = 78586
89 + 78497 = 78586
107 + 78479 = 78586
149 + 78437 = 78586
239 + 78347 = 78586
269 + 78317 = 78586

Showing the first eight; more decompositions exist.
