Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719628, here are decompositions:

37 + 8719591 = 8719628
61 + 8719567 = 8719628
79 + 8719549 = 8719628
109 + 8719519 = 8719628
367 + 8719261 = 8719628
409 + 8719219 = 8719628
487 + 8719141 = 8719628
571 + 8719057 = 8719628

Showing the first eight; more decompositions exist.
