Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603326, here are decompositions:

17 + 31603309 = 31603326
67 + 31603259 = 31603326
179 + 31603147 = 31603326
317 + 31603009 = 31603326
353 + 31602973 = 31603326
367 + 31602959 = 31603326
409 + 31602917 = 31603326
449 + 31602877 = 31603326

Showing the first eight; more decompositions exist.
