Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513158, here are decompositions:

127 + 513031 = 513158
157 + 513001 = 513158
181 + 512977 = 513158
199 + 512959 = 513158
229 + 512929 = 513158
241 + 512917 = 513158
337 + 512821 = 513158
379 + 512779 = 513158

Showing the first eight; more decompositions exist.
