Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671590, here are decompositions:

7 + 8671583 = 8671590
17 + 8671573 = 8671590
41 + 8671549 = 8671590
71 + 8671519 = 8671590
73 + 8671517 = 8671590
79 + 8671511 = 8671590
89 + 8671501 = 8671590
127 + 8671463 = 8671590

Showing the first eight; more decompositions exist.
