Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627814, here are decompositions:

3 + 31627811 = 31627814
13 + 31627801 = 31627814
61 + 31627753 = 31627814
241 + 31627573 = 31627814
271 + 31627543 = 31627814
277 + 31627537 = 31627814
313 + 31627501 = 31627814
331 + 31627483 = 31627814

Showing the first eight; more decompositions exist.
