Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513578, here are decompositions:

67 + 513511 = 513578
97 + 513481 = 513578
139 + 513439 = 513578
151 + 513427 = 513578
181 + 513397 = 513578
211 + 513367 = 513578
271 + 513307 = 513578
409 + 513169 = 513578

Showing the first eight; more decompositions exist.
