Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603470, here are decompositions:

43 + 31603427 = 31603470
89 + 31603381 = 31603470
103 + 31603367 = 31603470
109 + 31603361 = 31603470
127 + 31603343 = 31603470
211 + 31603259 = 31603470
277 + 31603193 = 31603470
313 + 31603157 = 31603470

Showing the first eight; more decompositions exist.
