Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586652, here are decompositions:

5 + 31586647 = 31586652
61 + 31586591 = 31586652
73 + 31586579 = 31586652
109 + 31586543 = 31586652
151 + 31586501 = 31586652
179 + 31586473 = 31586652
191 + 31586461 = 31586652
313 + 31586339 = 31586652

Showing the first eight; more decompositions exist.
