Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516694, here are decompositions:

61 + 31516633 = 31516694
67 + 31516627 = 31516694
127 + 31516567 = 31516694
151 + 31516543 = 31516694
193 + 31516501 = 31516694
211 + 31516483 = 31516694
271 + 31516423 = 31516694
283 + 31516411 = 31516694

Showing the first eight; more decompositions exist.
