Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574494, here are decompositions:

5 + 31574489 = 31574494
41 + 31574453 = 31574494
131 + 31574363 = 31574494
167 + 31574327 = 31574494
191 + 31574303 = 31574494
197 + 31574297 = 31574494
233 + 31574261 = 31574494
293 + 31574201 = 31574494

Showing the first eight; more decompositions exist.
