Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601272, here are decompositions:

5 + 31601267 = 31601272
173 + 31601099 = 31601272
389 + 31600883 = 31601272
449 + 31600823 = 31601272
569 + 31600703 = 31601272
653 + 31600619 = 31601272
743 + 31600529 = 31601272
761 + 31600511 = 31601272

Showing the first eight; more decompositions exist.
