Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671632, here are decompositions:

43 + 8671589 = 8671632
59 + 8671573 = 8671632
83 + 8671549 = 8671632
113 + 8671519 = 8671632
131 + 8671501 = 8671632
163 + 8671469 = 8671632
191 + 8671441 = 8671632
223 + 8671409 = 8671632

Showing the first eight; more decompositions exist.
