Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615926, here are decompositions:

5 + 31615921 = 31615926
7 + 31615919 = 31615926
79 + 31615847 = 31615926
163 + 31615763 = 31615926
197 + 31615729 = 31615926
257 + 31615669 = 31615926
263 + 31615663 = 31615926
317 + 31615609 = 31615926

Showing the first eight; more decompositions exist.
