Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603346, here are decompositions:

3 + 31603343 = 31603346
37 + 31603309 = 31603346
97 + 31603249 = 31603346
199 + 31603147 = 31603346
223 + 31603123 = 31603346
337 + 31603009 = 31603346
373 + 31602973 = 31603346
487 + 31602859 = 31603346

Showing the first eight; more decompositions exist.
