Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621744, here are decompositions:

37 + 8621707 = 8621744
67 + 8621677 = 8621744
127 + 8621617 = 8621744
163 + 8621581 = 8621744
193 + 8621551 = 8621744
277 + 8621467 = 8621744
331 + 8621413 = 8621744
367 + 8621377 = 8621744

Showing the first eight; more decompositions exist.
