Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514516, here are decompositions:

3 + 31514513 = 31514516
37 + 31514479 = 31514516
43 + 31514473 = 31514516
67 + 31514449 = 31514516
97 + 31514419 = 31514516
277 + 31514239 = 31514516
367 + 31514149 = 31514516
373 + 31514143 = 31514516

Showing the first eight; more decompositions exist.
