Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477588, here are decompositions:

5 + 31477583 = 31477588
11 + 31477577 = 31477588
17 + 31477571 = 31477588
239 + 31477349 = 31477588
509 + 31477079 = 31477588
521 + 31477067 = 31477588
641 + 31476947 = 31477588
977 + 31476611 = 31477588

Showing the first eight; more decompositions exist.
