Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524670, here are decompositions:

29 + 31524641 = 31524670
83 + 31524587 = 31524670
101 + 31524569 = 31524670
137 + 31524533 = 31524670
251 + 31524419 = 31524670
503 + 31524167 = 31524670
509 + 31524161 = 31524670
563 + 31524107 = 31524670

Showing the first eight; more decompositions exist.
