Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729102, here are decompositions:

3 + 8729099 = 8729102
43 + 8729059 = 8729102
139 + 8728963 = 8729102
181 + 8728921 = 8729102
199 + 8728903 = 8729102
439 + 8728663 = 8729102
523 + 8728579 = 8729102
619 + 8728483 = 8729102

Showing the first eight; more decompositions exist.
