Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553346, here are decompositions:

7 + 31553339 = 31553346
67 + 31553279 = 31553346
73 + 31553273 = 31553346
113 + 31553233 = 31553346
127 + 31553219 = 31553346
163 + 31553183 = 31553346
257 + 31553089 = 31553346
269 + 31553077 = 31553346

Showing the first eight; more decompositions exist.
