Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718386, here are decompositions:

37 + 8718349 = 8718386
43 + 8718343 = 8718386
73 + 8718313 = 8718386
109 + 8718277 = 8718386
139 + 8718247 = 8718386
223 + 8718163 = 8718386
277 + 8718109 = 8718386
283 + 8718103 = 8718386

Showing the first eight; more decompositions exist.
