Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555274, here are decompositions:

7 + 31555267 = 31555274
31 + 31555243 = 31555274
103 + 31555171 = 31555274
181 + 31555093 = 31555274
193 + 31555081 = 31555274
211 + 31555063 = 31555274
313 + 31554961 = 31555274
433 + 31554841 = 31555274

Showing the first eight; more decompositions exist.
