Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554722, here are decompositions:

13 + 31554709 = 31554722
103 + 31554619 = 31554722
109 + 31554613 = 31554722
139 + 31554583 = 31554722
151 + 31554571 = 31554722
181 + 31554541 = 31554722
211 + 31554511 = 31554722
229 + 31554493 = 31554722

Showing the first eight; more decompositions exist.
