Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601136, here are decompositions:

37 + 31601099 = 31601136
53 + 31601083 = 31601136
59 + 31601077 = 31601136
113 + 31601023 = 31601136
167 + 31600969 = 31601136
179 + 31600957 = 31601136
277 + 31600859 = 31601136
293 + 31600843 = 31601136

Showing the first eight; more decompositions exist.
