Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554412, here are decompositions:

3 + 31554409 = 31554412
11 + 31554401 = 31554412
233 + 31554179 = 31554412
251 + 31554161 = 31554412
269 + 31554143 = 31554412
401 + 31554011 = 31554412
419 + 31553993 = 31554412
509 + 31553903 = 31554412

Showing the first eight; more decompositions exist.
