Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554426, here are decompositions:

17 + 31554409 = 31554426
89 + 31554337 = 31554426
139 + 31554287 = 31554426
227 + 31554199 = 31554426
263 + 31554163 = 31554426
283 + 31554143 = 31554426
349 + 31554077 = 31554426
353 + 31554073 = 31554426

Showing the first eight; more decompositions exist.
