Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627670, here are decompositions:

31 + 31627639 = 31627670
43 + 31627627 = 31627670
97 + 31627573 = 31627670
103 + 31627567 = 31627670
127 + 31627543 = 31627670
313 + 31627357 = 31627670
337 + 31627333 = 31627670
367 + 31627303 = 31627670

Showing the first eight; more decompositions exist.
