Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601792, here are decompositions:

163 + 31601629 = 31601792
223 + 31601569 = 31601792
241 + 31601551 = 31601792
283 + 31601509 = 31601792
433 + 31601359 = 31601792
601 + 31601191 = 31601792
613 + 31601179 = 31601792
709 + 31601083 = 31601792

Showing the first eight; more decompositions exist.
