Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601338, here are decompositions:

71 + 31601267 = 31601338
239 + 31601099 = 31601338
479 + 31600859 = 31601338
521 + 31600817 = 31601338
617 + 31600721 = 31601338
719 + 31600619 = 31601338
809 + 31600529 = 31601338
827 + 31600511 = 31601338

Showing the first eight; more decompositions exist.
