Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524134, here are decompositions:

43 + 31524091 = 31524134
181 + 31523953 = 31524134
193 + 31523941 = 31524134
283 + 31523851 = 31524134
331 + 31523803 = 31524134
373 + 31523761 = 31524134
487 + 31523647 = 31524134
613 + 31523521 = 31524134

Showing the first eight; more decompositions exist.
