Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524130, here are decompositions:

23 + 31524107 = 31524130
83 + 31524047 = 31524130
107 + 31524023 = 31524130
191 + 31523939 = 31524130
461 + 31523669 = 31524130
479 + 31523651 = 31524130
593 + 31523537 = 31524130
653 + 31523477 = 31524130

Showing the first eight; more decompositions exist.
