Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553350, here are decompositions:

11 + 31553339 = 31553350
29 + 31553321 = 31553350
71 + 31553279 = 31553350
89 + 31553261 = 31553350
131 + 31553219 = 31553350
137 + 31553213 = 31553350
149 + 31553201 = 31553350
167 + 31553183 = 31553350

Showing the first eight; more decompositions exist.
