Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554434, here are decompositions:

73 + 31554361 = 31554434
97 + 31554337 = 31554434
151 + 31554283 = 31554434
193 + 31554241 = 31554434
271 + 31554163 = 31554434
313 + 31554121 = 31554434
421 + 31554013 = 31554434
601 + 31553833 = 31554434

Showing the first eight; more decompositions exist.
