Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992490, here are decompositions:

29 + 992461 = 992490
41 + 992449 = 992490
53 + 992437 = 992490
61 + 992429 = 992490
73 + 992417 = 992490
97 + 992393 = 992490
127 + 992363 = 992490
131 + 992359 = 992490

Showing the first eight; more decompositions exist.
