Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619750, here are decompositions:

37 + 31619713 = 31619750
67 + 31619683 = 31619750
103 + 31619647 = 31619750
139 + 31619611 = 31619750
193 + 31619557 = 31619750
223 + 31619527 = 31619750
229 + 31619521 = 31619750
241 + 31619509 = 31619750

Showing the first eight; more decompositions exist.
