Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010890, here are decompositions:

29 + 1010861 = 1010890
47 + 1010843 = 1010890
107 + 1010783 = 1010890
131 + 1010759 = 1010890
137 + 1010753 = 1010890
173 + 1010717 = 1010890
263 + 1010627 = 1010890
311 + 1010579 = 1010890

Showing the first eight; more decompositions exist.
