Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623268, here are decompositions:

11 + 31623257 = 31623268
59 + 31623209 = 31623268
101 + 31623167 = 31623268
227 + 31623041 = 31623268
317 + 31622951 = 31623268
431 + 31622837 = 31623268
491 + 31622777 = 31623268
569 + 31622699 = 31623268

Showing the first eight; more decompositions exist.
