Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524782, here are decompositions:

19 + 31524763 = 31524782
61 + 31524721 = 31524782
109 + 31524673 = 31524782
139 + 31524643 = 31524782
241 + 31524541 = 31524782
283 + 31524499 = 31524782
313 + 31524469 = 31524782
379 + 31524403 = 31524782

Showing the first eight; more decompositions exist.
