Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543676, here are decompositions:

7 + 31543669 = 31543676
97 + 31543579 = 31543676
223 + 31543453 = 31543676
433 + 31543243 = 31543676
457 + 31543219 = 31543676
607 + 31543069 = 31543676
709 + 31542967 = 31543676
727 + 31542949 = 31543676

Showing the first eight; more decompositions exist.
