Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472094, here are decompositions:

41 + 31472053 = 31472094
53 + 31472041 = 31472094
83 + 31472011 = 31472094
103 + 31471991 = 31472094
127 + 31471967 = 31472094
193 + 31471901 = 31472094
211 + 31471883 = 31472094
263 + 31471831 = 31472094

Showing the first eight; more decompositions exist.
