Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627616, here are decompositions:

43 + 31627573 = 31627616
73 + 31627543 = 31627616
79 + 31627537 = 31627616
283 + 31627333 = 31627616
313 + 31627303 = 31627616
367 + 31627249 = 31627616
373 + 31627243 = 31627616
379 + 31627237 = 31627616

Showing the first eight; more decompositions exist.
