Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543262, here are decompositions:

19 + 31543243 = 31543262
31 + 31543231 = 31543262
43 + 31543219 = 31543262
193 + 31543069 = 31543262
271 + 31542991 = 31543262
313 + 31542949 = 31543262
433 + 31542829 = 31543262
463 + 31542799 = 31543262

Showing the first eight; more decompositions exist.
