Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516614, here are decompositions:

11 + 31516603 = 31516614
43 + 31516571 = 31516614
47 + 31516567 = 31516614
71 + 31516543 = 31516614
113 + 31516501 = 31516614
131 + 31516483 = 31516614
191 + 31516423 = 31516614
257 + 31516357 = 31516614

Showing the first eight; more decompositions exist.
