Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627742, here are decompositions:

29 + 8627713 = 8627742
41 + 8627701 = 8627742
43 + 8627699 = 8627742
61 + 8627681 = 8627742
103 + 8627639 = 8627742
131 + 8627611 = 8627742
139 + 8627603 = 8627742
173 + 8627569 = 8627742

Showing the first eight; more decompositions exist.
