Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739540, here are decompositions:

11 + 8739529 = 8739540
37 + 8739503 = 8739540
41 + 8739499 = 8739540
59 + 8739481 = 8739540
107 + 8739433 = 8739540
109 + 8739431 = 8739540
149 + 8739391 = 8739540
151 + 8739389 = 8739540

Showing the first eight; more decompositions exist.
