Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603396, here are decompositions:

3 + 31603393 = 31603396
29 + 31603367 = 31603396
53 + 31603343 = 31603396
137 + 31603259 = 31603396
239 + 31603157 = 31603396
257 + 31603139 = 31603396
317 + 31603079 = 31603396
479 + 31602917 = 31603396

Showing the first eight; more decompositions exist.
