Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544018, here are decompositions:

7 + 31544011 = 31544018
31 + 31543987 = 31544018
241 + 31543777 = 31544018
307 + 31543711 = 31544018
349 + 31543669 = 31544018
439 + 31543579 = 31544018
487 + 31543531 = 31544018
787 + 31543231 = 31544018

Showing the first eight; more decompositions exist.
