Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586936, here are decompositions:

67 + 31586869 = 31586936
97 + 31586839 = 31586936
127 + 31586809 = 31586936
193 + 31586743 = 31586936
229 + 31586707 = 31586936
439 + 31586497 = 31586936
463 + 31586473 = 31586936
859 + 31586077 = 31586936

Showing the first eight; more decompositions exist.
