Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621486, here are decompositions:

7 + 8621479 = 8621486
19 + 8621467 = 8621486
43 + 8621443 = 8621486
73 + 8621413 = 8621486
109 + 8621377 = 8621486
277 + 8621209 = 8621486
397 + 8621089 = 8621486
409 + 8621077 = 8621486

Showing the first eight; more decompositions exist.
