Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574412, here are decompositions:

43 + 31574369 = 31574412
83 + 31574329 = 31574412
109 + 31574303 = 31574412
151 + 31574261 = 31574412
179 + 31574233 = 31574412
211 + 31574201 = 31574412
239 + 31574173 = 31574412
281 + 31574131 = 31574412

Showing the first eight; more decompositions exist.
