Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508172, here are decompositions:

13 + 508159 = 508172
43 + 508129 = 508172
139 + 508033 = 508172
151 + 508021 = 508172
163 + 508009 = 508172
193 + 507979 = 508172
211 + 507961 = 508172
271 + 507901 = 508172

Showing the first eight; more decompositions exist.
