Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513188, here are decompositions:

19 + 513169 = 513188
31 + 513157 = 513188
79 + 513109 = 513188
157 + 513031 = 513188
199 + 512989 = 513188
211 + 512977 = 513188
229 + 512959 = 513188
271 + 512917 = 513188

Showing the first eight; more decompositions exist.
