Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448548, here are decompositions:

29 + 31448519 = 31448548
41 + 31448507 = 31448548
101 + 31448447 = 31448548
167 + 31448381 = 31448548
179 + 31448369 = 31448548
227 + 31448321 = 31448548
239 + 31448309 = 31448548
251 + 31448297 = 31448548

Showing the first eight; more decompositions exist.
