Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610850, here are decompositions:

59 + 31610791 = 31610850
71 + 31610779 = 31610850
79 + 31610771 = 31610850
109 + 31610741 = 31610850
127 + 31610723 = 31610850
211 + 31610639 = 31610850
263 + 31610587 = 31610850
269 + 31610581 = 31610850

Showing the first eight; more decompositions exist.
