Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603534, here are decompositions:

23 + 31603511 = 31603534
47 + 31603487 = 31603534
107 + 31603427 = 31603534
167 + 31603367 = 31603534
173 + 31603361 = 31603534
191 + 31603343 = 31603534
461 + 31603073 = 31603534
617 + 31602917 = 31603534

Showing the first eight; more decompositions exist.
