Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601468, here are decompositions:

61 + 31601407 = 31601468
109 + 31601359 = 31601468
127 + 31601341 = 31601468
277 + 31601191 = 31601468
331 + 31601137 = 31601468
499 + 31600969 = 31601468
607 + 31600861 = 31601468
727 + 31600741 = 31601468

Showing the first eight; more decompositions exist.
