Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601726, here are decompositions:

3 + 31601723 = 31601726
19 + 31601707 = 31601726
97 + 31601629 = 31601726
157 + 31601569 = 31601726
199 + 31601527 = 31601726
367 + 31601359 = 31601726
379 + 31601347 = 31601726
463 + 31601263 = 31601726

Showing the first eight; more decompositions exist.
