Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553368, here are decompositions:

17 + 31553351 = 31553368
29 + 31553339 = 31553368
47 + 31553321 = 31553368
89 + 31553279 = 31553368
107 + 31553261 = 31553368
149 + 31553219 = 31553368
167 + 31553201 = 31553368
191 + 31553177 = 31553368

Showing the first eight; more decompositions exist.
