Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719578, here are decompositions:

5 + 8719573 = 8719578
11 + 8719567 = 8719578
29 + 8719549 = 8719578
37 + 8719541 = 8719578
59 + 8719519 = 8719578
137 + 8719441 = 8719578
157 + 8719421 = 8719578
199 + 8719379 = 8719578

Showing the first eight; more decompositions exist.
