Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742906, here are decompositions:

19 + 8742887 = 8742906
59 + 8742847 = 8742906
89 + 8742817 = 8742906
127 + 8742779 = 8742906
167 + 8742739 = 8742906
229 + 8742677 = 8742906
233 + 8742673 = 8742906
269 + 8742637 = 8742906

Showing the first eight; more decompositions exist.
