Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601464, here are decompositions:

47 + 31601417 = 31601464
53 + 31601411 = 31601464
71 + 31601393 = 31601464
107 + 31601357 = 31601464
197 + 31601267 = 31601464
641 + 31600823 = 31601464
647 + 31600817 = 31601464
743 + 31600721 = 31601464

Showing the first eight; more decompositions exist.
