Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603206, here are decompositions:

13 + 31603193 = 31603206
59 + 31603147 = 31603206
67 + 31603139 = 31603206
83 + 31603123 = 31603206
97 + 31603109 = 31603206
127 + 31603079 = 31603206
179 + 31603027 = 31603206
197 + 31603009 = 31603206

Showing the first eight; more decompositions exist.
