Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499056, here are decompositions:

23 + 31499033 = 31499056
53 + 31499003 = 31499056
89 + 31498967 = 31499056
107 + 31498949 = 31499056
227 + 31498829 = 31499056
293 + 31498763 = 31499056
353 + 31498703 = 31499056
509 + 31498547 = 31499056

Showing the first eight; more decompositions exist.
