Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627910, here are decompositions:

7 + 31627903 = 31627910
31 + 31627879 = 31627910
109 + 31627801 = 31627910
157 + 31627753 = 31627910
271 + 31627639 = 31627910
283 + 31627627 = 31627910
337 + 31627573 = 31627910
367 + 31627543 = 31627910

Showing the first eight; more decompositions exist.
