Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533430, here are decompositions:

17 + 31533413 = 31533430
41 + 31533389 = 31533430
59 + 31533371 = 31533430
239 + 31533191 = 31533430
263 + 31533167 = 31533430
281 + 31533149 = 31533430
311 + 31533119 = 31533430
431 + 31532999 = 31533430

Showing the first eight; more decompositions exist.
