Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603962, here are decompositions:

29 + 31603933 = 31603962
31 + 31603931 = 31603962
43 + 31603919 = 31603962
73 + 31603889 = 31603962
83 + 31603879 = 31603962
211 + 31603751 = 31603962
223 + 31603739 = 31603962
241 + 31603721 = 31603962

Showing the first eight; more decompositions exist.
