Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705722, here are decompositions:

41 + 8705681 = 8705722
83 + 8705639 = 8705722
149 + 8705573 = 8705722
173 + 8705549 = 8705722
191 + 8705531 = 8705722
239 + 8705483 = 8705722
269 + 8705453 = 8705722
281 + 8705441 = 8705722

Showing the first eight; more decompositions exist.
