Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448376, here are decompositions:

7 + 31448369 = 31448376
53 + 31448323 = 31448376
67 + 31448309 = 31448376
73 + 31448303 = 31448376
79 + 31448297 = 31448376
83 + 31448293 = 31448376
227 + 31448149 = 31448376
307 + 31448069 = 31448376

Showing the first eight; more decompositions exist.
