Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568274, here are decompositions:

7 + 31568267 = 31568274
47 + 31568227 = 31568274
53 + 31568221 = 31568274
71 + 31568203 = 31568274
151 + 31568123 = 31568274
167 + 31568107 = 31568274
191 + 31568083 = 31568274
233 + 31568041 = 31568274

Showing the first eight; more decompositions exist.
