Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989902, here are decompositions:

29 + 989873 = 989902
71 + 989831 = 989902
149 + 989753 = 989902
239 + 989663 = 989902
461 + 989441 = 989902
479 + 989423 = 989902
491 + 989411 = 989902
521 + 989381 = 989902

Showing the first eight; more decompositions exist.
