Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543292, here are decompositions:

19 + 31543273 = 31543292
61 + 31543231 = 31543292
73 + 31543219 = 31543292
223 + 31543069 = 31543292
283 + 31543009 = 31543292
349 + 31542943 = 31543292
463 + 31542829 = 31543292
661 + 31542631 = 31543292

Showing the first eight; more decompositions exist.
