Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516276, here are decompositions:

23 + 31516253 = 31516276
137 + 31516139 = 31516276
167 + 31516109 = 31516276
173 + 31516103 = 31516276
269 + 31516007 = 31516276
383 + 31515893 = 31516276
419 + 31515857 = 31516276
509 + 31515767 = 31516276

Showing the first eight; more decompositions exist.
