Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630722, here are decompositions:

53 + 8630669 = 8630722
59 + 8630663 = 8630722
83 + 8630639 = 8630722
131 + 8630591 = 8630722
239 + 8630483 = 8630722
431 + 8630291 = 8630722
479 + 8630243 = 8630722
491 + 8630231 = 8630722

Showing the first eight; more decompositions exist.
