Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633620, here are decompositions:

53 + 8633567 = 8633620
131 + 8633489 = 8633620
167 + 8633453 = 8633620
197 + 8633423 = 8633620
239 + 8633381 = 8633620
257 + 8633363 = 8633620
293 + 8633327 = 8633620
383 + 8633237 = 8633620

Showing the first eight; more decompositions exist.
