Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617586, here are decompositions:

37 + 8617549 = 8617586
67 + 8617519 = 8617586
73 + 8617513 = 8617586
139 + 8617447 = 8617586
349 + 8617237 = 8617586
379 + 8617207 = 8617586
409 + 8617177 = 8617586
433 + 8617153 = 8617586

Showing the first eight; more decompositions exist.
