Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523926, here are decompositions:

173 + 31523753 = 31523926
257 + 31523669 = 31523926
293 + 31523633 = 31523926
347 + 31523579 = 31523926
389 + 31523537 = 31523926
449 + 31523477 = 31523926
617 + 31523309 = 31523926
647 + 31523279 = 31523926

Showing the first eight; more decompositions exist.
