Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601458, here are decompositions:

41 + 31601417 = 31601458
47 + 31601411 = 31601458
101 + 31601357 = 31601458
191 + 31601267 = 31601458
359 + 31601099 = 31601458
599 + 31600859 = 31601458
641 + 31600817 = 31601458
659 + 31600799 = 31601458

Showing the first eight; more decompositions exist.
