Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603348, here are decompositions:

5 + 31603343 = 31603348
89 + 31603259 = 31603348
191 + 31603157 = 31603348
239 + 31603109 = 31603348
269 + 31603079 = 31603348
389 + 31602959 = 31603348
431 + 31602917 = 31603348
449 + 31602899 = 31603348

Showing the first eight; more decompositions exist.
