Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553488, here are decompositions:

101 + 31553387 = 31553488
137 + 31553351 = 31553488
149 + 31553339 = 31553488
167 + 31553321 = 31553488
227 + 31553261 = 31553488
269 + 31553219 = 31553488
311 + 31553177 = 31553488
419 + 31553069 = 31553488

Showing the first eight; more decompositions exist.
