Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554494, here are decompositions:

31 + 31554463 = 31554494
61 + 31554433 = 31554494
157 + 31554337 = 31554494
211 + 31554283 = 31554494
313 + 31554181 = 31554494
331 + 31554163 = 31554494
373 + 31554121 = 31554494
421 + 31554073 = 31554494

Showing the first eight; more decompositions exist.
