Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739906, here are decompositions:

5 + 8739901 = 8739906
23 + 8739883 = 8739906
29 + 8739877 = 8739906
37 + 8739869 = 8739906
79 + 8739827 = 8739906
83 + 8739823 = 8739906
103 + 8739803 = 8739906
137 + 8739769 = 8739906

Showing the first eight; more decompositions exist.
