Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627692, here are decompositions:

43 + 31627649 = 31627692
53 + 31627639 = 31627692
149 + 31627543 = 31627692
181 + 31627511 = 31627692
191 + 31627501 = 31627692
281 + 31627411 = 31627692
359 + 31627333 = 31627692
373 + 31627319 = 31627692

Showing the first eight; more decompositions exist.
