Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553394, here are decompositions:

7 + 31553387 = 31553394
11 + 31553383 = 31553394
43 + 31553351 = 31553394
73 + 31553321 = 31553394
181 + 31553213 = 31553394
193 + 31553201 = 31553394
211 + 31553183 = 31553394
233 + 31553161 = 31553394

Showing the first eight; more decompositions exist.
