Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621012, here are decompositions:

3 + 8621009 = 8621012
19 + 8620993 = 8621012
61 + 8620951 = 8621012
139 + 8620873 = 8621012
151 + 8620861 = 8621012
349 + 8620663 = 8621012
373 + 8620639 = 8621012
409 + 8620603 = 8621012

Showing the first eight; more decompositions exist.
