Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455096, here are decompositions:

97 + 31454999 = 31455096
139 + 31454957 = 31455096
173 + 31454923 = 31455096
193 + 31454903 = 31455096
223 + 31454873 = 31455096
229 + 31454867 = 31455096
269 + 31454827 = 31455096
313 + 31454783 = 31455096

Showing the first eight; more decompositions exist.
