Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554584, here are decompositions:

13 + 31554571 = 31554584
43 + 31554541 = 31554584
67 + 31554517 = 31554584
73 + 31554511 = 31554584
151 + 31554433 = 31554584
223 + 31554361 = 31554584
421 + 31554163 = 31554584
463 + 31554121 = 31554584

Showing the first eight; more decompositions exist.
