Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637658, here are decompositions:

17 + 8637641 = 8637658
41 + 8637617 = 8637658
47 + 8637611 = 8637658
131 + 8637527 = 8637658
137 + 8637521 = 8637658
149 + 8637509 = 8637658
167 + 8637491 = 8637658
191 + 8637467 = 8637658

Showing the first eight; more decompositions exist.
