Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513398, here are decompositions:

31 + 513367 = 513398
79 + 513319 = 513398
229 + 513169 = 513398
241 + 513157 = 513398
331 + 513067 = 513398
367 + 513031 = 513398
397 + 513001 = 513398
409 + 512989 = 513398

Showing the first eight; more decompositions exist.
