Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537114, here are decompositions:

17 + 31537097 = 31537114
71 + 31537043 = 31537114
113 + 31537001 = 31537114
131 + 31536983 = 31537114
197 + 31536917 = 31537114
251 + 31536863 = 31537114
293 + 31536821 = 31537114
383 + 31536731 = 31537114

Showing the first eight; more decompositions exist.
