Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476268, here are decompositions:

17 + 31476251 = 31476268
29 + 31476239 = 31476268
149 + 31476119 = 31476268
251 + 31476017 = 31476268
359 + 31475909 = 31476268
419 + 31475849 = 31476268
491 + 31475777 = 31476268
587 + 31475681 = 31476268

Showing the first eight; more decompositions exist.
