Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604054, here are decompositions:

3 + 31604051 = 31604054
67 + 31603987 = 31604054
211 + 31603843 = 31604054
337 + 31603717 = 31604054
373 + 31603681 = 31604054
397 + 31603657 = 31604054
487 + 31603567 = 31604054
661 + 31603393 = 31604054

Showing the first eight; more decompositions exist.
