Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617742, here are decompositions:

43 + 8617699 = 8617742
61 + 8617681 = 8617742
181 + 8617561 = 8617742
193 + 8617549 = 8617742
223 + 8617519 = 8617742
229 + 8617513 = 8617742
409 + 8617333 = 8617742
541 + 8617201 = 8617742

Showing the first eight; more decompositions exist.
