Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524172, here are decompositions:

5 + 31524167 = 31524172
11 + 31524161 = 31524172
149 + 31524023 = 31524172
233 + 31523939 = 31524172
419 + 31523753 = 31524172
503 + 31523669 = 31524172
521 + 31523651 = 31524172
593 + 31523579 = 31524172

Showing the first eight; more decompositions exist.
