Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603056, here are decompositions:

29 + 31603027 = 31603056
47 + 31603009 = 31603056
83 + 31602973 = 31603056
97 + 31602959 = 31603056
139 + 31602917 = 31603056
157 + 31602899 = 31603056
179 + 31602877 = 31603056
193 + 31602863 = 31603056

Showing the first eight; more decompositions exist.
