Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477636, here are decompositions:

53 + 31477583 = 31477636
59 + 31477577 = 31477636
83 + 31477553 = 31477636
257 + 31477379 = 31477636
347 + 31477289 = 31477636
557 + 31477079 = 31477636
569 + 31477067 = 31477636
677 + 31476959 = 31477636

Showing the first eight; more decompositions exist.
