Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638974, here are decompositions:

7 + 8638967 = 8638974
23 + 8638951 = 8638974
37 + 8638937 = 8638974
41 + 8638933 = 8638974
83 + 8638891 = 8638974
107 + 8638867 = 8638974
131 + 8638843 = 8638974
167 + 8638807 = 8638974

Showing the first eight; more decompositions exist.
