Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637948, here are decompositions:

5 + 8637943 = 8637948
19 + 8637929 = 8637948
79 + 8637869 = 8637948
101 + 8637847 = 8637948
127 + 8637821 = 8637948
157 + 8637791 = 8637948
199 + 8637749 = 8637948
251 + 8637697 = 8637948

Showing the first eight; more decompositions exist.
