Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529076, here are decompositions:

23 + 31529053 = 31529076
79 + 31528997 = 31529076
83 + 31528993 = 31529076
107 + 31528969 = 31529076
109 + 31528967 = 31529076
167 + 31528909 = 31529076
223 + 31528853 = 31529076
233 + 31528843 = 31529076

Showing the first eight; more decompositions exist.
