Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537474, here are decompositions:

5 + 31537469 = 31537474
41 + 31537433 = 31537474
83 + 31537391 = 31537474
167 + 31537307 = 31537474
251 + 31537223 = 31537474
347 + 31537127 = 31537474
431 + 31537043 = 31537474
491 + 31536983 = 31537474

Showing the first eight; more decompositions exist.
