Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009902, here are decompositions:

29 + 1009873 = 1009902
43 + 1009859 = 1009902
59 + 1009843 = 1009902
83 + 1009819 = 1009902
233 + 1009669 = 1009902
251 + 1009651 = 1009902
281 + 1009621 = 1009902
293 + 1009609 = 1009902

Showing the first eight; more decompositions exist.
