Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603404, here are decompositions:

11 + 31603393 = 31603404
23 + 31603381 = 31603404
37 + 31603367 = 31603404
43 + 31603361 = 31603404
61 + 31603343 = 31603404
211 + 31603193 = 31603404
257 + 31603147 = 31603404
263 + 31603141 = 31603404

Showing the first eight; more decompositions exist.
