Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513228, here are decompositions:

59 + 513169 = 513228
61 + 513167 = 513228
71 + 513157 = 513228
97 + 513131 = 513228
127 + 513101 = 513228
181 + 513047 = 513228
197 + 513031 = 513228
211 + 513017 = 513228

Showing the first eight; more decompositions exist.
