Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603186, here are decompositions:

29 + 31603157 = 31603186
47 + 31603139 = 31603186
107 + 31603079 = 31603186
113 + 31603073 = 31603186
227 + 31602959 = 31603186
269 + 31602917 = 31603186
383 + 31602803 = 31603186
599 + 31602587 = 31603186

Showing the first eight; more decompositions exist.
