Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601154, here are decompositions:

17 + 31601137 = 31601154
71 + 31601083 = 31601154
103 + 31601051 = 31601154
113 + 31601041 = 31601154
131 + 31601023 = 31601154
197 + 31600957 = 31601154
271 + 31600883 = 31601154
293 + 31600861 = 31601154

Showing the first eight; more decompositions exist.
