Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575332, here are decompositions:

31 + 31575301 = 31575332
181 + 31575151 = 31575332
193 + 31575139 = 31575332
241 + 31575091 = 31575332
421 + 31574911 = 31575332
631 + 31574701 = 31575332
643 + 31574689 = 31575332
661 + 31574671 = 31575332

Showing the first eight; more decompositions exist.
