Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455094, here are decompositions:

23 + 31455071 = 31455094
53 + 31455041 = 31455094
137 + 31454957 = 31455094
191 + 31454903 = 31455094
227 + 31454867 = 31455094
257 + 31454837 = 31455094
311 + 31454783 = 31455094
353 + 31454741 = 31455094

Showing the first eight; more decompositions exist.
