Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739572, here are decompositions:

43 + 8739529 = 8739572
73 + 8739499 = 8739572
109 + 8739463 = 8739572
139 + 8739433 = 8739572
181 + 8739391 = 8739572
223 + 8739349 = 8739572
241 + 8739331 = 8739572
379 + 8739193 = 8739572

Showing the first eight; more decompositions exist.
