Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682142, here are decompositions:

101 + 8682041 = 8682142
173 + 8681969 = 8682142
311 + 8681831 = 8682142
353 + 8681789 = 8682142
449 + 8681693 = 8682142
479 + 8681663 = 8682142
503 + 8681639 = 8682142
563 + 8681579 = 8682142

Showing the first eight; more decompositions exist.
