Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586214, here are decompositions:

43 + 31586171 = 31586214
67 + 31586147 = 31586214
73 + 31586141 = 31586214
83 + 31586131 = 31586214
113 + 31586101 = 31586214
137 + 31586077 = 31586214
157 + 31586057 = 31586214
211 + 31586003 = 31586214

Showing the first eight; more decompositions exist.
