Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527334, here are decompositions:

11 + 31527323 = 31527334
17 + 31527317 = 31527334
23 + 31527311 = 31527334
101 + 31527233 = 31527334
191 + 31527143 = 31527334
227 + 31527107 = 31527334
257 + 31527077 = 31527334
317 + 31527017 = 31527334

Showing the first eight; more decompositions exist.
