Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603264, here are decompositions:

3 + 31603261 = 31603264
5 + 31603259 = 31603264
71 + 31603193 = 31603264
107 + 31603157 = 31603264
191 + 31603073 = 31603264
347 + 31602917 = 31603264
401 + 31602863 = 31603264
461 + 31602803 = 31603264

Showing the first eight; more decompositions exist.
