Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523176, here are decompositions:

149 + 31523027 = 31523176
173 + 31523003 = 31523176
197 + 31522979 = 31523176
239 + 31522937 = 31523176
353 + 31522823 = 31523176
563 + 31522613 = 31523176
593 + 31522583 = 31523176
647 + 31522529 = 31523176

Showing the first eight; more decompositions exist.
