Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524672, here are decompositions:

29 + 31524643 = 31524672
31 + 31524641 = 31524672
103 + 31524569 = 31524672
131 + 31524541 = 31524672
139 + 31524533 = 31524672
149 + 31524523 = 31524672
163 + 31524509 = 31524672
173 + 31524499 = 31524672

Showing the first eight; more decompositions exist.
