Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555354, here are decompositions:

23 + 31555331 = 31555354
41 + 31555313 = 31555354
101 + 31555253 = 31555354
167 + 31555187 = 31555354
197 + 31555157 = 31555354
293 + 31555061 = 31555354
461 + 31554893 = 31555354
491 + 31554863 = 31555354

Showing the first eight; more decompositions exist.
