Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528734, here are decompositions:

5 + 31528729 = 31528734
11 + 31528723 = 31528734
37 + 31528697 = 31528734
101 + 31528633 = 31528734
113 + 31528621 = 31528734
233 + 31528501 = 31528734
283 + 31528451 = 31528734
397 + 31528337 = 31528734

Showing the first eight; more decompositions exist.
