Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524470, here are decompositions:

67 + 31524403 = 31524470
127 + 31524343 = 31524470
139 + 31524331 = 31524470
193 + 31524277 = 31524470
199 + 31524271 = 31524470
277 + 31524193 = 31524470
337 + 31524133 = 31524470
379 + 31524091 = 31524470

Showing the first eight; more decompositions exist.
