Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554456, here are decompositions:

7 + 31554449 = 31554456
23 + 31554433 = 31554456
47 + 31554409 = 31554456
173 + 31554283 = 31554456
257 + 31554199 = 31554456
277 + 31554179 = 31554456
293 + 31554163 = 31554456
313 + 31554143 = 31554456

Showing the first eight; more decompositions exist.
