Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78562, here are decompositions:

23 + 78539 = 78562
53 + 78509 = 78562
83 + 78479 = 78562
251 + 78311 = 78562
359 + 78203 = 78562
383 + 78179 = 78562
389 + 78173 = 78562
461 + 78101 = 78562

Showing the first eight; more decompositions exist.
