Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637426, here are decompositions:

47 + 8637379 = 8637426
53 + 8637373 = 8637426
89 + 8637337 = 8637426
103 + 8637323 = 8637426
107 + 8637319 = 8637426
137 + 8637289 = 8637426
163 + 8637263 = 8637426
173 + 8637253 = 8637426

Showing the first eight; more decompositions exist.
