Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028902, here are decompositions:

29 + 1028873 = 1028902
59 + 1028843 = 1028902
233 + 1028669 = 1028902
239 + 1028663 = 1028902
431 + 1028471 = 1028902
491 + 1028411 = 1028902
509 + 1028393 = 1028902
569 + 1028333 = 1028902

Showing the first eight; more decompositions exist.
