Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554630, here are decompositions:

11 + 31554619 = 31554630
13 + 31554617 = 31554630
17 + 31554613 = 31554630
47 + 31554583 = 31554630
59 + 31554571 = 31554630
61 + 31554569 = 31554630
89 + 31554541 = 31554630
103 + 31554527 = 31554630

Showing the first eight; more decompositions exist.
