Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603296, here are decompositions:

37 + 31603259 = 31603296
47 + 31603249 = 31603296
103 + 31603193 = 31603296
139 + 31603157 = 31603296
149 + 31603147 = 31603296
157 + 31603139 = 31603296
173 + 31603123 = 31603296
223 + 31603073 = 31603296

Showing the first eight; more decompositions exist.
