Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617862, here are decompositions:

109 + 8617753 = 8617862
163 + 8617699 = 8617862
181 + 8617681 = 8617862
313 + 8617549 = 8617862
349 + 8617513 = 8617862
571 + 8617291 = 8617862
601 + 8617261 = 8617862
661 + 8617201 = 8617862

Showing the first eight; more decompositions exist.
