Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603368, here are decompositions:

7 + 31603361 = 31603368
59 + 31603309 = 31603368
107 + 31603261 = 31603368
109 + 31603259 = 31603368
211 + 31603157 = 31603368
227 + 31603141 = 31603368
229 + 31603139 = 31603368
257 + 31603111 = 31603368

Showing the first eight; more decompositions exist.
