Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671626, here are decompositions:

37 + 8671589 = 8671626
43 + 8671583 = 8671626
53 + 8671573 = 8671626
107 + 8671519 = 8671626
109 + 8671517 = 8671626
127 + 8671499 = 8671626
157 + 8671469 = 8671626
163 + 8671463 = 8671626

Showing the first eight; more decompositions exist.
