Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513662, here are decompositions:

41 + 31513621 = 31513662
83 + 31513579 = 31513662
101 + 31513561 = 31513662
239 + 31513423 = 31513662
251 + 31513411 = 31513662
331 + 31513331 = 31513662
353 + 31513309 = 31513662
359 + 31513303 = 31513662

Showing the first eight; more decompositions exist.
