Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553382, here are decompositions:

13 + 31553369 = 31553382
23 + 31553359 = 31553382
31 + 31553351 = 31553382
43 + 31553339 = 31553382
61 + 31553321 = 31553382
103 + 31553279 = 31553382
109 + 31553273 = 31553382
149 + 31553233 = 31553382

Showing the first eight; more decompositions exist.
