Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533772, here are decompositions:

3 + 31533769 = 31533772
113 + 31533659 = 31533772
131 + 31533641 = 31533772
173 + 31533599 = 31533772
191 + 31533581 = 31533772
239 + 31533533 = 31533772
311 + 31533461 = 31533772
359 + 31533413 = 31533772

Showing the first eight; more decompositions exist.
