Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601146, here are decompositions:

47 + 31601099 = 31601146
263 + 31600883 = 31601146
347 + 31600799 = 31601146
443 + 31600703 = 31601146
617 + 31600529 = 31601146
653 + 31600493 = 31601146
827 + 31600319 = 31601146
839 + 31600307 = 31601146

Showing the first eight; more decompositions exist.
