Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707180, here are decompositions:

89 + 8707091 = 8707180
149 + 8707031 = 8707180
173 + 8707007 = 8707180
197 + 8706983 = 8707180
227 + 8706953 = 8707180
233 + 8706947 = 8707180
311 + 8706869 = 8707180
347 + 8706833 = 8707180

Showing the first eight; more decompositions exist.
