Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448476, here are decompositions:

29 + 31448447 = 31448476
53 + 31448423 = 31448476
107 + 31448369 = 31448476
167 + 31448309 = 31448476
173 + 31448303 = 31448476
179 + 31448297 = 31448476
419 + 31448057 = 31448476
443 + 31448033 = 31448476

Showing the first eight; more decompositions exist.
