Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028894, here are decompositions:

157 + 1028737 = 1028894
211 + 1028683 = 1028894
277 + 1028617 = 1028894
313 + 1028581 = 1028894
337 + 1028557 = 1028894
421 + 1028473 = 1028894
457 + 1028437 = 1028894
577 + 1028317 = 1028894

Showing the first eight; more decompositions exist.
