Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554704, here are decompositions:

37 + 31554667 = 31554704
67 + 31554637 = 31554704
73 + 31554631 = 31554704
163 + 31554541 = 31554704
193 + 31554511 = 31554704
211 + 31554493 = 31554704
241 + 31554463 = 31554704
271 + 31554433 = 31554704

Showing the first eight; more decompositions exist.
