Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553358, here are decompositions:

7 + 31553351 = 31553358
19 + 31553339 = 31553358
37 + 31553321 = 31553358
79 + 31553279 = 31553358
97 + 31553261 = 31553358
139 + 31553219 = 31553358
157 + 31553201 = 31553358
181 + 31553177 = 31553358

Showing the first eight; more decompositions exist.
