Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574334, here are decompositions:

5 + 31574329 = 31574334
7 + 31574327 = 31574334
31 + 31574303 = 31574334
37 + 31574297 = 31574334
73 + 31574261 = 31574334
101 + 31574233 = 31574334
131 + 31574203 = 31574334
227 + 31574107 = 31574334

Showing the first eight; more decompositions exist.
