Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637490, here are decompositions:

23 + 8637467 = 8637490
41 + 8637449 = 8637490
149 + 8637341 = 8637490
167 + 8637323 = 8637490
179 + 8637311 = 8637490
227 + 8637263 = 8637490
233 + 8637257 = 8637490
263 + 8637227 = 8637490

Showing the first eight; more decompositions exist.
