Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524654, here are decompositions:

11 + 31524643 = 31524654
13 + 31524641 = 31524654
47 + 31524607 = 31524654
67 + 31524587 = 31524654
113 + 31524541 = 31524654
131 + 31524523 = 31524654
137 + 31524517 = 31524654
251 + 31524403 = 31524654

Showing the first eight; more decompositions exist.
