Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537134, here are decompositions:

7 + 31537127 = 31537134
37 + 31537097 = 31537134
47 + 31537087 = 31537134
107 + 31537027 = 31537134
131 + 31537003 = 31537134
151 + 31536983 = 31537134
191 + 31536943 = 31537134
197 + 31536937 = 31537134

Showing the first eight; more decompositions exist.
