Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651662, here are decompositions:

23 + 8651639 = 8651662
53 + 8651609 = 8651662
59 + 8651603 = 8651662
83 + 8651579 = 8651662
113 + 8651549 = 8651662
233 + 8651429 = 8651662
263 + 8651399 = 8651662
401 + 8651261 = 8651662

Showing the first eight; more decompositions exist.
