Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612442, here are decompositions:

5 + 8612437 = 8612442
19 + 8612423 = 8612442
29 + 8612413 = 8612442
31 + 8612411 = 8612442
43 + 8612399 = 8612442
131 + 8612311 = 8612442
149 + 8612293 = 8612442
199 + 8612243 = 8612442

Showing the first eight; more decompositions exist.
