Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627740, here are decompositions:

41 + 8627699 = 8627740
47 + 8627693 = 8627740
59 + 8627681 = 8627740
101 + 8627639 = 8627740
113 + 8627627 = 8627740
131 + 8627609 = 8627740
137 + 8627603 = 8627740
167 + 8627573 = 8627740

Showing the first eight; more decompositions exist.
