Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574350, here are decompositions:

23 + 31574327 = 31574350
47 + 31574303 = 31574350
53 + 31574297 = 31574350
89 + 31574261 = 31574350
149 + 31574201 = 31574350
251 + 31574099 = 31574350
257 + 31574093 = 31574350
383 + 31573967 = 31574350

Showing the first eight; more decompositions exist.
