Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726386, here are decompositions:

3 + 8726383 = 8726386
5 + 8726381 = 8726386
23 + 8726363 = 8726386
29 + 8726357 = 8726386
113 + 8726273 = 8726386
293 + 8726093 = 8726386
359 + 8726027 = 8726386
509 + 8725877 = 8726386

Showing the first eight; more decompositions exist.
