Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603260, here are decompositions:

11 + 31603249 = 31603260
67 + 31603193 = 31603260
103 + 31603157 = 31603260
113 + 31603147 = 31603260
137 + 31603123 = 31603260
149 + 31603111 = 31603260
151 + 31603109 = 31603260
181 + 31603079 = 31603260

Showing the first eight; more decompositions exist.
