Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528874, here are decompositions:

31 + 31528843 = 31528874
43 + 31528831 = 31528874
61 + 31528813 = 31528874
67 + 31528807 = 31528874
73 + 31528801 = 31528874
151 + 31528723 = 31528874
241 + 31528633 = 31528874
373 + 31528501 = 31528874

Showing the first eight; more decompositions exist.
