Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603136, here are decompositions:

13 + 31603123 = 31603136
109 + 31603027 = 31603136
127 + 31603009 = 31603136
163 + 31602973 = 31603136
277 + 31602859 = 31603136
283 + 31602853 = 31603136
373 + 31602763 = 31603136
457 + 31602679 = 31603136

Showing the first eight; more decompositions exist.
