Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627658, here are decompositions:

19 + 8627639 = 8627658
31 + 8627627 = 8627658
41 + 8627617 = 8627658
47 + 8627611 = 8627658
89 + 8627569 = 8627658
97 + 8627561 = 8627658
131 + 8627527 = 8627658
191 + 8627467 = 8627658

Showing the first eight; more decompositions exist.
