Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725086, here are decompositions:

47 + 8725039 = 8725086
103 + 8724983 = 8725086
137 + 8724949 = 8725086
157 + 8724929 = 8725086
239 + 8724847 = 8725086
283 + 8724803 = 8725086
347 + 8724739 = 8725086
367 + 8724719 = 8725086

Showing the first eight; more decompositions exist.
