Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617988, here are decompositions:

61 + 8617927 = 8617988
151 + 8617837 = 8617988
307 + 8617681 = 8617988
439 + 8617549 = 8617988
541 + 8617447 = 8617988
571 + 8617417 = 8617988
607 + 8617381 = 8617988
661 + 8617327 = 8617988

Showing the first eight; more decompositions exist.
