Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525112, here are decompositions:

349 + 31524763 = 31525112
439 + 31524673 = 31525112
571 + 31524541 = 31525112
613 + 31524499 = 31525112
643 + 31524469 = 31525112
709 + 31524403 = 31525112
769 + 31524343 = 31525112
811 + 31524301 = 31525112

Showing the first eight; more decompositions exist.
