Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601132, here are decompositions:

109 + 31601023 = 31601132
139 + 31600993 = 31601132
163 + 31600969 = 31601132
271 + 31600861 = 31601132
331 + 31600801 = 31601132
349 + 31600783 = 31601132
379 + 31600753 = 31601132
439 + 31600693 = 31601132

Showing the first eight; more decompositions exist.
