Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713390, here are decompositions:

17 + 8713373 = 8713390
41 + 8713349 = 8713390
71 + 8713319 = 8713390
83 + 8713307 = 8713390
173 + 8713217 = 8713390
197 + 8713193 = 8713390
233 + 8713157 = 8713390
263 + 8713127 = 8713390

Showing the first eight; more decompositions exist.
