Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537066, here are decompositions:

17 + 31537049 = 31537066
23 + 31537043 = 31537066
83 + 31536983 = 31537066
107 + 31536959 = 31537066
149 + 31536917 = 31537066
293 + 31536773 = 31537066
347 + 31536719 = 31537066
359 + 31536707 = 31537066

Showing the first eight; more decompositions exist.
