Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609478, here are decompositions:

5 + 8609473 = 8609478
19 + 8609459 = 8609478
29 + 8609449 = 8609478
37 + 8609441 = 8609478
47 + 8609431 = 8609478
67 + 8609411 = 8609478
107 + 8609371 = 8609478
131 + 8609347 = 8609478

Showing the first eight; more decompositions exist.
