Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555334, here are decompositions:

3 + 31555331 = 31555334
7 + 31555327 = 31555334
37 + 31555297 = 31555334
67 + 31555267 = 31555334
163 + 31555171 = 31555334
193 + 31555141 = 31555334
241 + 31555093 = 31555334
271 + 31555063 = 31555334

Showing the first eight; more decompositions exist.
