Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637634, here are decompositions:

17 + 8637617 = 8637634
23 + 8637611 = 8637634
107 + 8637527 = 8637634
113 + 8637521 = 8637634
167 + 8637467 = 8637634
293 + 8637341 = 8637634
311 + 8637323 = 8637634
431 + 8637203 = 8637634

Showing the first eight; more decompositions exist.
