Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577464, here are decompositions:

47 + 31577417 = 31577464
71 + 31577393 = 31577464
101 + 31577363 = 31577464
173 + 31577291 = 31577464
383 + 31577081 = 31577464
563 + 31576901 = 31577464
761 + 31576703 = 31577464
881 + 31576583 = 31577464

Showing the first eight; more decompositions exist.
