Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553352, here are decompositions:

13 + 31553339 = 31553352
31 + 31553321 = 31553352
73 + 31553279 = 31553352
79 + 31553273 = 31553352
139 + 31553213 = 31553352
151 + 31553201 = 31553352
191 + 31553161 = 31553352
263 + 31553089 = 31553352

Showing the first eight; more decompositions exist.
