Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586502, here are decompositions:

5 + 31586497 = 31586502
19 + 31586483 = 31586502
29 + 31586473 = 31586502
41 + 31586461 = 31586502
151 + 31586351 = 31586502
163 + 31586339 = 31586502
191 + 31586311 = 31586502
229 + 31586273 = 31586502

Showing the first eight; more decompositions exist.
