Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574606, here are decompositions:

43 + 31574563 = 31574606
109 + 31574497 = 31574606
127 + 31574479 = 31574606
139 + 31574467 = 31574606
157 + 31574449 = 31574606
163 + 31574443 = 31574606
277 + 31574329 = 31574606
373 + 31574233 = 31574606

Showing the first eight; more decompositions exist.
