Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554454, here are decompositions:

5 + 31554449 = 31554454
53 + 31554401 = 31554454
167 + 31554287 = 31554454
293 + 31554161 = 31554454
311 + 31554143 = 31554454
443 + 31554011 = 31554454
461 + 31553993 = 31554454
467 + 31553987 = 31554454

Showing the first eight; more decompositions exist.
