Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023906, here are decompositions:

67 + 1023839 = 1023906
73 + 1023833 = 1023906
137 + 1023769 = 1023906
173 + 1023733 = 1023906
263 + 1023643 = 1023906
349 + 1023557 = 1023906
419 + 1023487 = 1023906
439 + 1023467 = 1023906

Showing the first eight; more decompositions exist.
