Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451324, here are decompositions:

31 + 31451293 = 31451324
277 + 31451047 = 31451324
433 + 31450891 = 31451324
523 + 31450801 = 31451324
601 + 31450723 = 31451324
937 + 31450387 = 31451324
1033 + 31450291 = 31451324
1117 + 31450207 = 31451324

Showing the first eight; more decompositions exist.
