Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637700, here are decompositions:

3 + 8637697 = 8637700
59 + 8637641 = 8637700
83 + 8637617 = 8637700
89 + 8637611 = 8637700
173 + 8637527 = 8637700
179 + 8637521 = 8637700
191 + 8637509 = 8637700
233 + 8637467 = 8637700

Showing the first eight; more decompositions exist.
