Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603384, here are decompositions:

3 + 31603381 = 31603384
17 + 31603367 = 31603384
23 + 31603361 = 31603384
41 + 31603343 = 31603384
191 + 31603193 = 31603384
227 + 31603157 = 31603384
311 + 31603073 = 31603384
467 + 31602917 = 31603384

Showing the first eight; more decompositions exist.
