Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513230, here are decompositions:

61 + 513169 = 513230
73 + 513157 = 513230
127 + 513103 = 513230
163 + 513067 = 513230
199 + 513031 = 513230
229 + 513001 = 513230
241 + 512989 = 513230
271 + 512959 = 513230

Showing the first eight; more decompositions exist.
