Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598948, here are decompositions:

37 + 31598911 = 31598948
61 + 31598887 = 31598948
109 + 31598839 = 31598948
499 + 31598449 = 31598948
547 + 31598401 = 31598948
571 + 31598377 = 31598948
709 + 31598239 = 31598948
757 + 31598191 = 31598948

Showing the first eight; more decompositions exist.
