Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729154, here are decompositions:

13 + 8729141 = 8729154
23 + 8729131 = 8729154
37 + 8729117 = 8729154
47 + 8729107 = 8729154
61 + 8729093 = 8729154
73 + 8729081 = 8729154
97 + 8729057 = 8729154
101 + 8729053 = 8729154

Showing the first eight; more decompositions exist.
