Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603474, here are decompositions:

47 + 31603427 = 31603474
107 + 31603367 = 31603474
113 + 31603361 = 31603474
131 + 31603343 = 31603474
281 + 31603193 = 31603474
317 + 31603157 = 31603474
401 + 31603073 = 31603474
557 + 31602917 = 31603474

Showing the first eight; more decompositions exist.
