Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516502, here are decompositions:

19 + 31516483 = 31516502
79 + 31516423 = 31516502
313 + 31516189 = 31516502
349 + 31516153 = 31516502
373 + 31516129 = 31516502
379 + 31516123 = 31516502
421 + 31516081 = 31516502
571 + 31515931 = 31516502

Showing the first eight; more decompositions exist.
