Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574414, here are decompositions:

181 + 31574233 = 31574414
211 + 31574203 = 31574414
241 + 31574173 = 31574414
283 + 31574131 = 31574414
307 + 31574107 = 31574414
367 + 31574047 = 31574414
373 + 31574041 = 31574414
457 + 31573957 = 31574414

Showing the first eight; more decompositions exist.
