Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577716, here are decompositions:

47 + 31577669 = 31577716
59 + 31577657 = 31577716
83 + 31577633 = 31577716
347 + 31577369 = 31577716
353 + 31577363 = 31577716
557 + 31577159 = 31577716
587 + 31577129 = 31577716
659 + 31577057 = 31577716

Showing the first eight; more decompositions exist.
