Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508142, here are decompositions:

13 + 508129 = 508142
109 + 508033 = 508142
163 + 507979 = 508142
181 + 507961 = 508142
223 + 507919 = 508142
241 + 507901 = 508142
571 + 507571 = 508142
619 + 507523 = 508142

Showing the first eight; more decompositions exist.
