Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622820, here are decompositions:

53 + 8622767 = 8622820
113 + 8622707 = 8622820
137 + 8622683 = 8622820
257 + 8622563 = 8622820
347 + 8622473 = 8622820
359 + 8622461 = 8622820
461 + 8622359 = 8622820
467 + 8622353 = 8622820

Showing the first eight; more decompositions exist.
