Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523866, here are decompositions:

113 + 31523753 = 31523866
197 + 31523669 = 31523866
233 + 31523633 = 31523866
389 + 31523477 = 31523866
467 + 31523399 = 31523866
557 + 31523309 = 31523866
587 + 31523279 = 31523866
599 + 31523267 = 31523866

Showing the first eight; more decompositions exist.
