Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603606, here are decompositions:

29 + 31603577 = 31603606
53 + 31603553 = 31603606
179 + 31603427 = 31603606
239 + 31603367 = 31603606
263 + 31603343 = 31603606
347 + 31603259 = 31603606
449 + 31603157 = 31603606
467 + 31603139 = 31603606

Showing the first eight; more decompositions exist.
