Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603254, here are decompositions:

5 + 31603249 = 31603254
61 + 31603193 = 31603254
97 + 31603157 = 31603254
107 + 31603147 = 31603254
113 + 31603141 = 31603254
131 + 31603123 = 31603254
181 + 31603073 = 31603254
227 + 31603027 = 31603254

Showing the first eight; more decompositions exist.
