Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601088, here are decompositions:

5 + 31601083 = 31601088
11 + 31601077 = 31601088
37 + 31601051 = 31601088
47 + 31601041 = 31601088
131 + 31600957 = 31601088
227 + 31600861 = 31601088
229 + 31600859 = 31601088
271 + 31600817 = 31601088

Showing the first eight; more decompositions exist.
