Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524262, here are decompositions:

5 + 31524257 = 31524262
101 + 31524161 = 31524262
239 + 31524023 = 31524262
251 + 31524011 = 31524262
461 + 31523801 = 31524262
509 + 31523753 = 31524262
593 + 31523669 = 31524262
683 + 31523579 = 31524262

Showing the first eight; more decompositions exist.
