Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705672, here are decompositions:

61 + 8705611 = 8705672
181 + 8705491 = 8705672
211 + 8705461 = 8705672
223 + 8705449 = 8705672
229 + 8705443 = 8705672
373 + 8705299 = 8705672
523 + 8705149 = 8705672
631 + 8705041 = 8705672

Showing the first eight; more decompositions exist.
