Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603584, here are decompositions:

7 + 31603577 = 31603584
17 + 31603567 = 31603584
31 + 31603553 = 31603584
73 + 31603511 = 31603584
97 + 31603487 = 31603584
157 + 31603427 = 31603584
191 + 31603393 = 31603584
223 + 31603361 = 31603584

Showing the first eight; more decompositions exist.
