Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524434, here are decompositions:

31 + 31524403 = 31524434
103 + 31524331 = 31524434
157 + 31524277 = 31524434
163 + 31524271 = 31524434
211 + 31524223 = 31524434
241 + 31524193 = 31524434
421 + 31524013 = 31524434
631 + 31523803 = 31524434

Showing the first eight; more decompositions exist.
