Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601268, here are decompositions:

5 + 31601263 = 31601268
89 + 31601179 = 31601268
131 + 31601137 = 31601268
191 + 31601077 = 31601268
227 + 31601041 = 31601268
311 + 31600957 = 31601268
409 + 31600859 = 31601268
467 + 31600801 = 31601268

Showing the first eight; more decompositions exist.
