Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639082, here are decompositions:

19 + 8639063 = 8639082
31 + 8639051 = 8639082
71 + 8639011 = 8639082
83 + 8638999 = 8639082
131 + 8638951 = 8639082
149 + 8638933 = 8639082
173 + 8638909 = 8639082
191 + 8638891 = 8639082

Showing the first eight; more decompositions exist.
