Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554582, here are decompositions:

11 + 31554571 = 31554582
13 + 31554569 = 31554582
41 + 31554541 = 31554582
43 + 31554539 = 31554582
71 + 31554511 = 31554582
89 + 31554493 = 31554582
109 + 31554473 = 31554582
149 + 31554433 = 31554582

Showing the first eight; more decompositions exist.
