Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448354, here are decompositions:

31 + 31448323 = 31448354
61 + 31448293 = 31448354
73 + 31448281 = 31448354
163 + 31448191 = 31448354
193 + 31448161 = 31448354
283 + 31448071 = 31448354
331 + 31448023 = 31448354
337 + 31448017 = 31448354

Showing the first eight; more decompositions exist.
