Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603062, here are decompositions:

53 + 31603009 = 31603062
89 + 31602973 = 31603062
103 + 31602959 = 31603062
131 + 31602931 = 31603062
163 + 31602899 = 31603062
199 + 31602863 = 31603062
269 + 31602793 = 31603062
373 + 31602689 = 31603062

Showing the first eight; more decompositions exist.
