Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000742, here are decompositions:

19 + 1000723 = 1000742
73 + 1000669 = 1000742
103 + 1000639 = 1000742
163 + 1000579 = 1000742
313 + 1000429 = 1000742
349 + 1000393 = 1000742
409 + 1000333 = 1000742
439 + 1000303 = 1000742

Showing the first eight; more decompositions exist.
