Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025512, here are decompositions:

3 + 1025509 = 1025512
29 + 1025483 = 1025512
53 + 1025459 = 1025512
179 + 1025333 = 1025512
233 + 1025279 = 1025512
239 + 1025273 = 1025512
251 + 1025261 = 1025512
281 + 1025231 = 1025512

Showing the first eight; more decompositions exist.
