Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637620, here are decompositions:

3 + 8637617 = 8637620
97 + 8637523 = 8637620
127 + 8637493 = 8637620
139 + 8637481 = 8637620
193 + 8637427 = 8637620
241 + 8637379 = 8637620
283 + 8637337 = 8637620
331 + 8637289 = 8637620

Showing the first eight; more decompositions exist.
