Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603468, here are decompositions:

41 + 31603427 = 31603468
101 + 31603367 = 31603468
107 + 31603361 = 31603468
311 + 31603157 = 31603468
359 + 31603109 = 31603468
389 + 31603079 = 31603468
509 + 31602959 = 31603468
569 + 31602899 = 31603468

Showing the first eight; more decompositions exist.
