Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448452, here are decompositions:

3 + 31448449 = 31448452
5 + 31448447 = 31448452
29 + 31448423 = 31448452
71 + 31448381 = 31448452
83 + 31448369 = 31448452
131 + 31448321 = 31448452
149 + 31448303 = 31448452
251 + 31448201 = 31448452

Showing the first eight; more decompositions exist.
