Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603554, here are decompositions:

43 + 31603511 = 31603554
67 + 31603487 = 31603554
127 + 31603427 = 31603554
173 + 31603381 = 31603554
193 + 31603361 = 31603554
211 + 31603343 = 31603554
293 + 31603261 = 31603554
397 + 31603157 = 31603554

Showing the first eight; more decompositions exist.
