Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496206, here are decompositions:

83 + 31496123 = 31496206
107 + 31496099 = 31496206
149 + 31496057 = 31496206
179 + 31496027 = 31496206
227 + 31495979 = 31496206
257 + 31495949 = 31496206
347 + 31495859 = 31496206
359 + 31495847 = 31496206

Showing the first eight; more decompositions exist.
