Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627922, here are decompositions:

19 + 31627903 = 31627922
43 + 31627879 = 31627922
61 + 31627861 = 31627922
283 + 31627639 = 31627922
349 + 31627573 = 31627922
379 + 31627543 = 31627922
421 + 31627501 = 31627922
439 + 31627483 = 31627922

Showing the first eight; more decompositions exist.
