Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603152, here are decompositions:

5 + 31603147 = 31603152
11 + 31603141 = 31603152
13 + 31603139 = 31603152
29 + 31603123 = 31603152
41 + 31603111 = 31603152
43 + 31603109 = 31603152
73 + 31603079 = 31603152
79 + 31603073 = 31603152

Showing the first eight; more decompositions exist.
