Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477316, here are decompositions:

103 + 31477213 = 31477316
109 + 31477207 = 31477316
463 + 31476853 = 31477316
487 + 31476829 = 31477316
613 + 31476703 = 31477316
709 + 31476607 = 31477316
769 + 31476547 = 31477316
859 + 31476457 = 31477316

Showing the first eight; more decompositions exist.
