Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989872, here are decompositions:

3 + 989869 = 989872
41 + 989831 = 989872
89 + 989783 = 989872
293 + 989579 = 989872
311 + 989561 = 989872
431 + 989441 = 989872
449 + 989423 = 989872
461 + 989411 = 989872

Showing the first eight; more decompositions exist.
