Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603914, here are decompositions:

37 + 31603877 = 31603914
71 + 31603843 = 31603914
113 + 31603801 = 31603914
157 + 31603757 = 31603914
163 + 31603751 = 31603914
193 + 31603721 = 31603914
197 + 31603717 = 31603914
233 + 31603681 = 31603914

Showing the first eight; more decompositions exist.
