Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603150, here are decompositions:

3 + 31603147 = 31603150
11 + 31603139 = 31603150
41 + 31603109 = 31603150
71 + 31603079 = 31603150
191 + 31602959 = 31603150
233 + 31602917 = 31603150
251 + 31602899 = 31603150
347 + 31602803 = 31603150

Showing the first eight; more decompositions exist.
