Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508158, here are decompositions:

29 + 508129 = 508158
61 + 508097 = 508158
67 + 508091 = 508158
71 + 508087 = 508158
137 + 508021 = 508158
139 + 508019 = 508158
149 + 508009 = 508158
179 + 507979 = 508158

Showing the first eight; more decompositions exist.
