Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637450, here are decompositions:

23 + 8637427 = 8637450
71 + 8637379 = 8637450
109 + 8637341 = 8637450
113 + 8637337 = 8637450
127 + 8637323 = 8637450
131 + 8637319 = 8637450
139 + 8637311 = 8637450
149 + 8637301 = 8637450

Showing the first eight; more decompositions exist.
