Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637342, here are decompositions:

5 + 8637337 = 8637342
19 + 8637323 = 8637342
23 + 8637319 = 8637342
31 + 8637311 = 8637342
41 + 8637301 = 8637342
53 + 8637289 = 8637342
79 + 8637263 = 8637342
89 + 8637253 = 8637342

Showing the first eight; more decompositions exist.
