Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603350, here are decompositions:

7 + 31603343 = 31603350
41 + 31603309 = 31603350
89 + 31603261 = 31603350
101 + 31603249 = 31603350
157 + 31603193 = 31603350
193 + 31603157 = 31603350
211 + 31603139 = 31603350
227 + 31603123 = 31603350

Showing the first eight; more decompositions exist.
