Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586650, here are decompositions:

3 + 31586647 = 31586650
23 + 31586627 = 31586650
59 + 31586591 = 31586650
71 + 31586579 = 31586650
107 + 31586543 = 31586650
113 + 31586537 = 31586650
149 + 31586501 = 31586650
167 + 31586483 = 31586650

Showing the first eight; more decompositions exist.
