Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542334, here are decompositions:

11 + 31542323 = 31542334
53 + 31542281 = 31542334
101 + 31542233 = 31542334
137 + 31542197 = 31542334
251 + 31542083 = 31542334
311 + 31542023 = 31542334
353 + 31541981 = 31542334
401 + 31541933 = 31542334

Showing the first eight; more decompositions exist.
