Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524154, here are decompositions:

47 + 31524107 = 31524154
107 + 31524047 = 31524154
131 + 31524023 = 31524154
353 + 31523801 = 31524154
401 + 31523753 = 31524154
503 + 31523651 = 31524154
521 + 31523633 = 31524154
617 + 31523537 = 31524154

Showing the first eight; more decompositions exist.
