Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83678, here are decompositions:

37 + 83641 = 83678
61 + 83617 = 83678
181 + 83497 = 83678
229 + 83449 = 83678
241 + 83437 = 83678
271 + 83407 = 83678
277 + 83401 = 83678
337 + 83341 = 83678

Showing the first eight; more decompositions exist.
