Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537014, here are decompositions:

11 + 31537003 = 31537014
13 + 31537001 = 31537014
23 + 31536991 = 31537014
31 + 31536983 = 31537014
71 + 31536943 = 31537014
97 + 31536917 = 31537014
151 + 31536863 = 31537014
167 + 31536847 = 31537014

Showing the first eight; more decompositions exist.
