Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524690, here are decompositions:

13 + 31524677 = 31524690
17 + 31524673 = 31524690
47 + 31524643 = 31524690
83 + 31524607 = 31524690
103 + 31524587 = 31524690
149 + 31524541 = 31524690
157 + 31524533 = 31524690
167 + 31524523 = 31524690

Showing the first eight; more decompositions exist.
