Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586952, here are decompositions:

11 + 31586941 = 31586952
13 + 31586939 = 31586952
31 + 31586921 = 31586952
73 + 31586879 = 31586952
83 + 31586869 = 31586952
113 + 31586839 = 31586952
139 + 31586813 = 31586952
149 + 31586803 = 31586952

Showing the first eight; more decompositions exist.
