Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603944, here are decompositions:

11 + 31603933 = 31603944
13 + 31603931 = 31603944
67 + 31603877 = 31603944
101 + 31603843 = 31603944
193 + 31603751 = 31603944
223 + 31603721 = 31603944
227 + 31603717 = 31603944
233 + 31603711 = 31603944

Showing the first eight; more decompositions exist.
