Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601296, here are decompositions:

29 + 31601267 = 31601296
197 + 31601099 = 31601296
479 + 31600817 = 31601296
563 + 31600733 = 31601296
593 + 31600703 = 31601296
677 + 31600619 = 31601296
773 + 31600523 = 31601296
887 + 31600409 = 31601296

Showing the first eight; more decompositions exist.
