Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627726, here are decompositions:

5 + 31627721 = 31627726
149 + 31627577 = 31627726
167 + 31627559 = 31627726
353 + 31627373 = 31627726
479 + 31627247 = 31627726
509 + 31627217 = 31627726
593 + 31627133 = 31627726
653 + 31627073 = 31627726

Showing the first eight; more decompositions exist.
