Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448514, here are decompositions:

7 + 31448507 = 31448514
67 + 31448447 = 31448514
101 + 31448413 = 31448514
137 + 31448377 = 31448514
191 + 31448323 = 31448514
193 + 31448321 = 31448514
211 + 31448303 = 31448514
233 + 31448281 = 31448514

Showing the first eight; more decompositions exist.
