Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537174, here are decompositions:

23 + 31537151 = 31537174
41 + 31537133 = 31537174
47 + 31537127 = 31537174
131 + 31537043 = 31537174
173 + 31537001 = 31537174
191 + 31536983 = 31537174
257 + 31536917 = 31537174
311 + 31536863 = 31537174

Showing the first eight; more decompositions exist.
