Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516946, here are decompositions:

67 + 31516879 = 31516946
127 + 31516819 = 31516946
157 + 31516789 = 31516946
193 + 31516753 = 31516946
277 + 31516669 = 31516946
313 + 31516633 = 31516946
379 + 31516567 = 31516946
463 + 31516483 = 31516946

Showing the first eight; more decompositions exist.
