Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627772, here are decompositions:

19 + 31627753 = 31627772
199 + 31627573 = 31627772
229 + 31627543 = 31627772
271 + 31627501 = 31627772
439 + 31627333 = 31627772
523 + 31627249 = 31627772
571 + 31627201 = 31627772
739 + 31627033 = 31627772

Showing the first eight; more decompositions exist.
