Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603006, here are decompositions:

47 + 31602959 = 31603006
89 + 31602917 = 31603006
107 + 31602899 = 31603006
317 + 31602689 = 31603006
359 + 31602647 = 31603006
419 + 31602587 = 31603006
467 + 31602539 = 31603006
509 + 31602497 = 31603006

Showing the first eight; more decompositions exist.
