Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461616, here are decompositions:

47 + 31461569 = 31461616
59 + 31461557 = 31461616
83 + 31461533 = 31461616
443 + 31461173 = 31461616
467 + 31461149 = 31461616
503 + 31461113 = 31461616
569 + 31461047 = 31461616
743 + 31460873 = 31461616

Showing the first eight; more decompositions exist.
