Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501208, here are decompositions:

5 + 501203 = 501208
11 + 501197 = 501208
17 + 501191 = 501208
131 + 501077 = 501208
179 + 501029 = 501208
251 + 500957 = 501208
317 + 500891 = 501208
347 + 500861 = 501208

Showing the first eight; more decompositions exist.
