Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568348, here are decompositions:

37 + 31568311 = 31568348
61 + 31568287 = 31568348
67 + 31568281 = 31568348
127 + 31568221 = 31568348
151 + 31568197 = 31568348
241 + 31568107 = 31568348
277 + 31568071 = 31568348
307 + 31568041 = 31568348

Showing the first eight; more decompositions exist.
