Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671228, here are decompositions:

101 + 8671127 = 8671228
131 + 8671097 = 8671228
197 + 8671031 = 8671228
239 + 8670989 = 8671228
281 + 8670947 = 8671228
359 + 8670869 = 8671228
617 + 8670611 = 8671228
677 + 8670551 = 8671228

Showing the first eight; more decompositions exist.
