Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601470, here are decompositions:

53 + 31601417 = 31601470
59 + 31601411 = 31601470
113 + 31601357 = 31601470
419 + 31601051 = 31601470
587 + 31600883 = 31601470
647 + 31600823 = 31601470
653 + 31600817 = 31601470
941 + 31600529 = 31601470

Showing the first eight; more decompositions exist.
