Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601192, here are decompositions:

13 + 31601179 = 31601192
109 + 31601083 = 31601192
151 + 31601041 = 31601192
199 + 31600993 = 31601192
223 + 31600969 = 31601192
331 + 31600861 = 31601192
349 + 31600843 = 31601192
409 + 31600783 = 31601192

Showing the first eight; more decompositions exist.
