Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725082, here are decompositions:

31 + 8725051 = 8725082
43 + 8725039 = 8725082
61 + 8725021 = 8725082
139 + 8724943 = 8725082
199 + 8724883 = 8725082
211 + 8724871 = 8725082
283 + 8724799 = 8725082
433 + 8724649 = 8725082

Showing the first eight; more decompositions exist.
