Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554536, here are decompositions:

19 + 31554517 = 31554536
43 + 31554493 = 31554536
73 + 31554463 = 31554536
103 + 31554433 = 31554536
127 + 31554409 = 31554536
199 + 31554337 = 31554536
337 + 31554199 = 31554536
373 + 31554163 = 31554536

Showing the first eight; more decompositions exist.
