Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554674, here are decompositions:

3 + 31554671 = 31554674
7 + 31554667 = 31554674
37 + 31554637 = 31554674
43 + 31554631 = 31554674
61 + 31554613 = 31554674
103 + 31554571 = 31554674
157 + 31554517 = 31554674
163 + 31554511 = 31554674

Showing the first eight; more decompositions exist.
