Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594272, here are decompositions:

79 + 31594193 = 31594272
109 + 31594163 = 31594272
113 + 31594159 = 31594272
139 + 31594133 = 31594272
191 + 31594081 = 31594272
211 + 31594061 = 31594272
223 + 31594049 = 31594272
233 + 31594039 = 31594272

Showing the first eight; more decompositions exist.
