Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524082, here are decompositions:

59 + 31524023 = 31524082
71 + 31524011 = 31524082
281 + 31523801 = 31524082
431 + 31523651 = 31524082
449 + 31523633 = 31524082
503 + 31523579 = 31524082
641 + 31523441 = 31524082
683 + 31523399 = 31524082

Showing the first eight; more decompositions exist.
