Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603596, here are decompositions:

19 + 31603577 = 31603596
29 + 31603567 = 31603596
43 + 31603553 = 31603596
107 + 31603489 = 31603596
109 + 31603487 = 31603596
229 + 31603367 = 31603596
337 + 31603259 = 31603596
347 + 31603249 = 31603596

Showing the first eight; more decompositions exist.
