Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609486, here are decompositions:

3 + 8609483 = 8609486
13 + 8609473 = 8609486
37 + 8609449 = 8609486
43 + 8609443 = 8609486
139 + 8609347 = 8609486
163 + 8609323 = 8609486
199 + 8609287 = 8609486
229 + 8609257 = 8609486

Showing the first eight; more decompositions exist.
