Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639516, here are decompositions:

73 + 8639443 = 8639516
103 + 8639413 = 8639516
367 + 8639149 = 8639516
373 + 8639143 = 8639516
397 + 8639119 = 8639516
409 + 8639107 = 8639516
607 + 8638909 = 8639516
673 + 8638843 = 8639516

Showing the first eight; more decompositions exist.
