Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617662, here are decompositions:

101 + 8617561 = 8617662
113 + 8617549 = 8617662
139 + 8617523 = 8617662
149 + 8617513 = 8617662
223 + 8617439 = 8617662
271 + 8617391 = 8617662
281 + 8617381 = 8617662
349 + 8617313 = 8617662

Showing the first eight; more decompositions exist.
