Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448454, here are decompositions:

5 + 31448449 = 31448454
7 + 31448447 = 31448454
31 + 31448423 = 31448454
41 + 31448413 = 31448454
73 + 31448381 = 31448454
131 + 31448323 = 31448454
151 + 31448303 = 31448454
157 + 31448297 = 31448454

Showing the first eight; more decompositions exist.
