Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597204, here are decompositions:

5 + 31597199 = 31597204
53 + 31597151 = 31597204
83 + 31597121 = 31597204
173 + 31597031 = 31597204
227 + 31596977 = 31597204
281 + 31596923 = 31597204
347 + 31596857 = 31597204
383 + 31596821 = 31597204

Showing the first eight; more decompositions exist.
