Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516484, here are decompositions:

61 + 31516423 = 31516484
73 + 31516411 = 31516484
127 + 31516357 = 31516484
151 + 31516333 = 31516484
157 + 31516327 = 31516484
283 + 31516201 = 31516484
331 + 31516153 = 31516484
397 + 31516087 = 31516484

Showing the first eight; more decompositions exist.
