Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613142, here are decompositions:

53 + 8613089 = 8613142
101 + 8613041 = 8613142
173 + 8612969 = 8613142
269 + 8612873 = 8613142
281 + 8612861 = 8613142
311 + 8612831 = 8613142
389 + 8612753 = 8613142
431 + 8612711 = 8613142

Showing the first eight; more decompositions exist.
