Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516376, here are decompositions:

19 + 31516357 = 31516376
43 + 31516333 = 31516376
79 + 31516297 = 31516376
139 + 31516237 = 31516376
193 + 31516183 = 31516376
223 + 31516153 = 31516376
277 + 31516099 = 31516376
349 + 31516027 = 31516376

Showing the first eight; more decompositions exist.
