Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601774, here are decompositions:

7 + 31601767 = 31601774
31 + 31601743 = 31601774
67 + 31601707 = 31601774
103 + 31601671 = 31601774
223 + 31601551 = 31601774
367 + 31601407 = 31601774
433 + 31601341 = 31601774
571 + 31601203 = 31601774

Showing the first eight; more decompositions exist.
