Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603016, here are decompositions:

7 + 31603009 = 31603016
43 + 31602973 = 31603016
139 + 31602877 = 31603016
157 + 31602859 = 31603016
163 + 31602853 = 31603016
223 + 31602793 = 31603016
337 + 31602679 = 31603016
499 + 31602517 = 31603016

Showing the first eight; more decompositions exist.
