Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671142, here are decompositions:

43 + 8671099 = 8671142
79 + 8671063 = 8671142
199 + 8670943 = 8671142
223 + 8670919 = 8671142
331 + 8670811 = 8671142
433 + 8670709 = 8671142
439 + 8670703 = 8671142
463 + 8670679 = 8671142

Showing the first eight; more decompositions exist.
