Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537294, here are decompositions:

23 + 31537271 = 31537294
71 + 31537223 = 31537294
167 + 31537127 = 31537294
197 + 31537097 = 31537294
251 + 31537043 = 31537294
293 + 31537001 = 31537294
311 + 31536983 = 31537294
431 + 31536863 = 31537294

Showing the first eight; more decompositions exist.
