Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621072, here are decompositions:

79 + 8620993 = 8621072
199 + 8620873 = 8621072
211 + 8620861 = 8621072
349 + 8620723 = 8621072
409 + 8620663 = 8621072
433 + 8620639 = 8621072
643 + 8620429 = 8621072
853 + 8620219 = 8621072

Showing the first eight; more decompositions exist.
