Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603266, here are decompositions:

5 + 31603261 = 31603266
7 + 31603259 = 31603266
17 + 31603249 = 31603266
73 + 31603193 = 31603266
109 + 31603157 = 31603266
127 + 31603139 = 31603266
157 + 31603109 = 31603266
193 + 31603073 = 31603266

Showing the first eight; more decompositions exist.
