Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78836, here are decompositions:

13 + 78823 = 78836
139 + 78697 = 78836
193 + 78643 = 78836
229 + 78607 = 78836
283 + 78553 = 78836
349 + 78487 = 78836
397 + 78439 = 78836
409 + 78427 = 78836

Showing the first eight; more decompositions exist.
