Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543522, here are decompositions:

41 + 31543481 = 31543522
71 + 31543451 = 31543522
173 + 31543349 = 31543522
191 + 31543331 = 31543522
359 + 31543163 = 31543522
389 + 31543133 = 31543522
419 + 31543103 = 31543522
443 + 31543079 = 31543522

Showing the first eight; more decompositions exist.
