Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543472, here are decompositions:

19 + 31543453 = 31543472
43 + 31543429 = 31543472
199 + 31543273 = 31543472
229 + 31543243 = 31543472
241 + 31543231 = 31543472
463 + 31543009 = 31543472
523 + 31542949 = 31543472
643 + 31542829 = 31543472

Showing the first eight; more decompositions exist.
