Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516876, here are decompositions:

89 + 31516787 = 31516876
173 + 31516703 = 31516876
179 + 31516697 = 31516876
257 + 31516619 = 31516876
263 + 31516613 = 31516876
317 + 31516559 = 31516876
353 + 31516523 = 31516876
383 + 31516493 = 31516876

Showing the first eight; more decompositions exist.
