Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516922, here are decompositions:

43 + 31516879 = 31516922
103 + 31516819 = 31516922
193 + 31516729 = 31516922
223 + 31516699 = 31516922
379 + 31516543 = 31516922
421 + 31516501 = 31516922
439 + 31516483 = 31516922
499 + 31516423 = 31516922

Showing the first eight; more decompositions exist.
