Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737668, here are decompositions:

11 + 8737657 = 8737668
41 + 8737627 = 8737668
97 + 8737571 = 8737668
139 + 8737529 = 8737668
167 + 8737501 = 8737668
179 + 8737489 = 8737668
241 + 8737427 = 8737668
311 + 8737357 = 8737668

Showing the first eight; more decompositions exist.
