Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516952, here are decompositions:

73 + 31516879 = 31516952
163 + 31516789 = 31516952
199 + 31516753 = 31516952
223 + 31516729 = 31516952
283 + 31516669 = 31516952
349 + 31516603 = 31516952
409 + 31516543 = 31516952
433 + 31516519 = 31516952

Showing the first eight; more decompositions exist.
