Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603074, here are decompositions:

47 + 31603027 = 31603074
101 + 31602973 = 31603074
157 + 31602917 = 31603074
197 + 31602877 = 31603074
211 + 31602863 = 31603074
271 + 31602803 = 31603074
281 + 31602793 = 31603074
311 + 31602763 = 31603074

Showing the first eight; more decompositions exist.
