Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601196, here are decompositions:

5 + 31601191 = 31601196
17 + 31601179 = 31601196
59 + 31601137 = 31601196
97 + 31601099 = 31601196
113 + 31601083 = 31601196
173 + 31601023 = 31601196
227 + 31600969 = 31601196
239 + 31600957 = 31601196

Showing the first eight; more decompositions exist.
