Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601426, here are decompositions:

19 + 31601407 = 31601426
67 + 31601359 = 31601426
79 + 31601347 = 31601426
163 + 31601263 = 31601426
223 + 31601203 = 31601426
349 + 31601077 = 31601426
433 + 31600993 = 31601426
457 + 31600969 = 31601426

Showing the first eight; more decompositions exist.
