Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568292, here are decompositions:

5 + 31568287 = 31568292
11 + 31568281 = 31568292
71 + 31568221 = 31568292
89 + 31568203 = 31568292
113 + 31568179 = 31568292
163 + 31568129 = 31568292
233 + 31568059 = 31568292
251 + 31568041 = 31568292

Showing the first eight; more decompositions exist.
