Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458468, here are decompositions:

17 + 31458451 = 31458468
31 + 31458437 = 31458468
37 + 31458431 = 31458468
89 + 31458379 = 31458468
137 + 31458331 = 31458468
157 + 31458311 = 31458468
191 + 31458277 = 31458468
229 + 31458239 = 31458468

Showing the first eight; more decompositions exist.
