Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533784, here are decompositions:

11 + 31533773 = 31533784
173 + 31533611 = 31533784
197 + 31533587 = 31533784
251 + 31533533 = 31533784
353 + 31533431 = 31533784
593 + 31533191 = 31533784
617 + 31533167 = 31533784
641 + 31533143 = 31533784

Showing the first eight; more decompositions exist.
