Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463866, here are decompositions:

17 + 31463849 = 31463866
23 + 31463843 = 31463866
59 + 31463807 = 31463866
107 + 31463759 = 31463866
149 + 31463717 = 31463866
347 + 31463519 = 31463866
359 + 31463507 = 31463866
383 + 31463483 = 31463866

Showing the first eight; more decompositions exist.
