Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620922, here are decompositions:

61 + 8620861 = 8620922
199 + 8620723 = 8620922
283 + 8620639 = 8620922
379 + 8620543 = 8620922
691 + 8620231 = 8620922
733 + 8620189 = 8620922
811 + 8620111 = 8620922
853 + 8620069 = 8620922

Showing the first eight; more decompositions exist.
