Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554452, here are decompositions:

3 + 31554449 = 31554452
19 + 31554433 = 31554452
43 + 31554409 = 31554452
211 + 31554241 = 31554452
271 + 31554181 = 31554452
331 + 31554121 = 31554452
379 + 31554073 = 31554452
409 + 31554043 = 31554452

Showing the first eight; more decompositions exist.
