Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543202, here are decompositions:

193 + 31543009 = 31543202
211 + 31542991 = 31543202
373 + 31542829 = 31543202
499 + 31542703 = 31543202
571 + 31542631 = 31543202
643 + 31542559 = 31543202
811 + 31542391 = 31543202
829 + 31542373 = 31543202

Showing the first eight; more decompositions exist.
