Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458466, here are decompositions:

29 + 31458437 = 31458466
47 + 31458419 = 31458466
89 + 31458377 = 31458466
167 + 31458299 = 31458466
227 + 31458239 = 31458466
269 + 31458197 = 31458466
293 + 31458173 = 31458466
353 + 31458113 = 31458466

Showing the first eight; more decompositions exist.
