Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533756, here are decompositions:

97 + 31533659 = 31533756
157 + 31533599 = 31533756
193 + 31533563 = 31533756
223 + 31533533 = 31533756
239 + 31533517 = 31533756
257 + 31533499 = 31533756
307 + 31533449 = 31533756
347 + 31533409 = 31533756

Showing the first eight; more decompositions exist.
