Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621516, here are decompositions:

37 + 8621479 = 8621516
73 + 8621443 = 8621516
103 + 8621413 = 8621516
139 + 8621377 = 8621516
307 + 8621209 = 8621516
373 + 8621143 = 8621516
433 + 8621083 = 8621516
439 + 8621077 = 8621516

Showing the first eight; more decompositions exist.
