Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603044, here are decompositions:

17 + 31603027 = 31603044
71 + 31602973 = 31603044
113 + 31602931 = 31603044
127 + 31602917 = 31603044
167 + 31602877 = 31603044
181 + 31602863 = 31603044
191 + 31602853 = 31603044
241 + 31602803 = 31603044

Showing the first eight; more decompositions exist.
