Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601506, here are decompositions:

17 + 31601489 = 31601506
89 + 31601417 = 31601506
113 + 31601393 = 31601506
149 + 31601357 = 31601506
239 + 31601267 = 31601506
647 + 31600859 = 31601506
683 + 31600823 = 31601506
773 + 31600733 = 31601506

Showing the first eight; more decompositions exist.
