Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009888, here are decompositions:

29 + 1009859 = 1009888
101 + 1009787 = 1009888
107 + 1009781 = 1009888
239 + 1009649 = 1009888
251 + 1009637 = 1009888
389 + 1009499 = 1009888
401 + 1009487 = 1009888
431 + 1009457 = 1009888

Showing the first eight; more decompositions exist.
