Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623256, here are decompositions:

47 + 31623209 = 31623256
83 + 31623173 = 31623256
89 + 31623167 = 31623256
233 + 31623023 = 31623256
317 + 31622939 = 31623256
419 + 31622837 = 31623256
479 + 31622777 = 31623256
557 + 31622699 = 31623256

Showing the first eight; more decompositions exist.
