Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701986, here are decompositions:

37 + 8701949 = 8701986
53 + 8701933 = 8701986
79 + 8701907 = 8701986
103 + 8701883 = 8701986
109 + 8701877 = 8701986
113 + 8701873 = 8701986
173 + 8701813 = 8701986
197 + 8701789 = 8701986

Showing the first eight; more decompositions exist.
