Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612478, here are decompositions:

5 + 8612473 = 8612478
41 + 8612437 = 8612478
67 + 8612411 = 8612478
79 + 8612399 = 8612478
131 + 8612347 = 8612478
167 + 8612311 = 8612478
179 + 8612299 = 8612478
257 + 8612221 = 8612478

Showing the first eight; more decompositions exist.
