Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524582, here are decompositions:

13 + 31524569 = 31524582
41 + 31524541 = 31524582
59 + 31524523 = 31524582
73 + 31524509 = 31524582
83 + 31524499 = 31524582
113 + 31524469 = 31524582
163 + 31524419 = 31524582
179 + 31524403 = 31524582

Showing the first eight; more decompositions exist.
