Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603608, here are decompositions:

31 + 31603577 = 31603608
41 + 31603567 = 31603608
89 + 31603519 = 31603608
97 + 31603511 = 31603608
181 + 31603427 = 31603608
227 + 31603381 = 31603608
241 + 31603367 = 31603608
347 + 31603261 = 31603608

Showing the first eight; more decompositions exist.
