Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603166, here are decompositions:

19 + 31603147 = 31603166
43 + 31603123 = 31603166
139 + 31603027 = 31603166
157 + 31603009 = 31603166
193 + 31602973 = 31603166
307 + 31602859 = 31603166
313 + 31602853 = 31603166
373 + 31602793 = 31603166

Showing the first eight; more decompositions exist.
