Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743386, here are decompositions:

7 + 8743379 = 8743386
19 + 8743367 = 8743386
37 + 8743349 = 8743386
59 + 8743327 = 8743386
107 + 8743279 = 8743386
109 + 8743277 = 8743386
173 + 8743213 = 8743386
283 + 8743103 = 8743386

Showing the first eight; more decompositions exist.
