Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477714, here are decompositions:

3 + 31477711 = 31477714
17 + 31477697 = 31477714
131 + 31477583 = 31477714
137 + 31477577 = 31477714
647 + 31477067 = 31477714
797 + 31476917 = 31477714
971 + 31476743 = 31477714
1091 + 31476623 = 31477714

Showing the first eight; more decompositions exist.
