Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603504, here are decompositions:

17 + 31603487 = 31603504
137 + 31603367 = 31603504
311 + 31603193 = 31603504
347 + 31603157 = 31603504
431 + 31603073 = 31603504
587 + 31602917 = 31603504
641 + 31602863 = 31603504
701 + 31602803 = 31603504

Showing the first eight; more decompositions exist.
