Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734878, here are decompositions:

37 + 8734841 = 8734878
59 + 8734819 = 8734878
71 + 8734807 = 8734878
109 + 8734769 = 8734878
137 + 8734741 = 8734878
149 + 8734729 = 8734878
181 + 8734697 = 8734878
239 + 8734639 = 8734878

Showing the first eight; more decompositions exist.
