Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586948, here are decompositions:

7 + 31586941 = 31586948
79 + 31586869 = 31586948
109 + 31586839 = 31586948
139 + 31586809 = 31586948
157 + 31586791 = 31586948
229 + 31586719 = 31586948
241 + 31586707 = 31586948
277 + 31586671 = 31586948

Showing the first eight; more decompositions exist.
