Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621162, here are decompositions:

19 + 8621143 = 8621162
61 + 8621101 = 8621162
73 + 8621089 = 8621162
79 + 8621083 = 8621162
211 + 8620951 = 8621162
439 + 8620723 = 8621162
499 + 8620663 = 8621162
523 + 8620639 = 8621162

Showing the first eight; more decompositions exist.
