Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603176, here are decompositions:

19 + 31603157 = 31603176
29 + 31603147 = 31603176
37 + 31603139 = 31603176
53 + 31603123 = 31603176
67 + 31603109 = 31603176
97 + 31603079 = 31603176
103 + 31603073 = 31603176
149 + 31603027 = 31603176

Showing the first eight; more decompositions exist.
