Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524404, here are decompositions:

61 + 31524343 = 31524404
73 + 31524331 = 31524404
103 + 31524301 = 31524404
127 + 31524277 = 31524404
181 + 31524223 = 31524404
211 + 31524193 = 31524404
271 + 31524133 = 31524404
313 + 31524091 = 31524404

Showing the first eight; more decompositions exist.
