Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554684, here are decompositions:

13 + 31554671 = 31554684
17 + 31554667 = 31554684
43 + 31554641 = 31554684
47 + 31554637 = 31554684
53 + 31554631 = 31554684
67 + 31554617 = 31554684
71 + 31554613 = 31554684
101 + 31554583 = 31554684

Showing the first eight; more decompositions exist.
