Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458522, here are decompositions:

41 + 31458481 = 31458522
71 + 31458451 = 31458522
103 + 31458419 = 31458522
149 + 31458373 = 31458522
191 + 31458331 = 31458522
211 + 31458311 = 31458522
223 + 31458299 = 31458522
283 + 31458239 = 31458522

Showing the first eight; more decompositions exist.
