Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007906, here are decompositions:

19 + 1007887 = 1007906
79 + 1007827 = 1007906
139 + 1007767 = 1007906
157 + 1007749 = 1007906
223 + 1007683 = 1007906
307 + 1007599 = 1007906
349 + 1007557 = 1007906
379 + 1007527 = 1007906

Showing the first eight; more decompositions exist.
