Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537846, here are decompositions:

3 + 31537843 = 31537846
23 + 31537823 = 31537846
617 + 31537229 = 31537846
719 + 31537127 = 31537846
797 + 31537049 = 31537846
863 + 31536983 = 31537846
887 + 31536959 = 31537846
929 + 31536917 = 31537846

Showing the first eight; more decompositions exist.
