Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719856, here are decompositions:

37 + 8719819 = 8719856
43 + 8719813 = 8719856
109 + 8719747 = 8719856
157 + 8719699 = 8719856
193 + 8719663 = 8719856
283 + 8719573 = 8719856
307 + 8719549 = 8719856
337 + 8719519 = 8719856

Showing the first eight; more decompositions exist.
