Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603524, here are decompositions:

5 + 31603519 = 31603524
13 + 31603511 = 31603524
37 + 31603487 = 31603524
97 + 31603427 = 31603524
131 + 31603393 = 31603524
157 + 31603367 = 31603524
163 + 31603361 = 31603524
181 + 31603343 = 31603524

Showing the first eight; more decompositions exist.
