Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458396, here are decompositions:

17 + 31458379 = 31458396
19 + 31458377 = 31458396
23 + 31458373 = 31458396
97 + 31458299 = 31458396
157 + 31458239 = 31458396
199 + 31458197 = 31458396
223 + 31458173 = 31458396
227 + 31458169 = 31458396

Showing the first eight; more decompositions exist.
