Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656822, here are decompositions:

89 + 8656733 = 8656822
101 + 8656721 = 8656822
131 + 8656691 = 8656822
233 + 8656589 = 8656822
311 + 8656511 = 8656822
353 + 8656469 = 8656822
359 + 8656463 = 8656822
389 + 8656433 = 8656822

Showing the first eight; more decompositions exist.
