Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628314, here are decompositions:

23 + 31628291 = 31628314
41 + 31628273 = 31628314
293 + 31628021 = 31628314
353 + 31627961 = 31628314
383 + 31627931 = 31628314
503 + 31627811 = 31628314
521 + 31627793 = 31628314
563 + 31627751 = 31628314

Showing the first eight; more decompositions exist.
