Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554564, here are decompositions:

23 + 31554541 = 31554564
37 + 31554527 = 31554564
47 + 31554517 = 31554564
53 + 31554511 = 31554564
71 + 31554493 = 31554564
101 + 31554463 = 31554564
131 + 31554433 = 31554564
163 + 31554401 = 31554564

Showing the first eight; more decompositions exist.
