Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555276, here are decompositions:

17 + 31555259 = 31555276
23 + 31555253 = 31555276
47 + 31555229 = 31555276
89 + 31555187 = 31555276
167 + 31555109 = 31555276
197 + 31555079 = 31555276
257 + 31555019 = 31555276
383 + 31554893 = 31555276

Showing the first eight; more decompositions exist.
