Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555336, here are decompositions:

5 + 31555331 = 31555336
17 + 31555319 = 31555336
23 + 31555313 = 31555336
47 + 31555289 = 31555336
83 + 31555253 = 31555336
107 + 31555229 = 31555336
149 + 31555187 = 31555336
179 + 31555157 = 31555336

Showing the first eight; more decompositions exist.
