Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621534, here are decompositions:

43 + 8621491 = 8621534
67 + 8621467 = 8621534
157 + 8621377 = 8621534
433 + 8621101 = 8621534
457 + 8621077 = 8621534
487 + 8621047 = 8621534
541 + 8620993 = 8621534
661 + 8620873 = 8621534

Showing the first eight; more decompositions exist.
