Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554662, here are decompositions:

3 + 31554659 = 31554662
31 + 31554631 = 31554662
43 + 31554619 = 31554662
79 + 31554583 = 31554662
151 + 31554511 = 31554662
199 + 31554463 = 31554662
229 + 31554433 = 31554662
379 + 31554283 = 31554662

Showing the first eight; more decompositions exist.
