Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637996, here are decompositions:

5 + 8637991 = 8637996
23 + 8637973 = 8637996
43 + 8637953 = 8637996
53 + 8637943 = 8637996
67 + 8637929 = 8637996
127 + 8637869 = 8637996
149 + 8637847 = 8637996
167 + 8637829 = 8637996

Showing the first eight; more decompositions exist.
