Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533706, here are decompositions:

47 + 31533659 = 31533706
107 + 31533599 = 31533706
173 + 31533533 = 31533706
257 + 31533449 = 31533706
293 + 31533413 = 31533706
317 + 31533389 = 31533706
557 + 31533149 = 31533706
563 + 31533143 = 31533706

Showing the first eight; more decompositions exist.
