Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524770, here are decompositions:

3 + 31524767 = 31524770
7 + 31524763 = 31524770
97 + 31524673 = 31524770
127 + 31524643 = 31524770
163 + 31524607 = 31524770
229 + 31524541 = 31524770
271 + 31524499 = 31524770
367 + 31524403 = 31524770

Showing the first eight; more decompositions exist.
