Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739582, here are decompositions:

53 + 8739529 = 8739582
79 + 8739503 = 8739582
83 + 8739499 = 8739582
101 + 8739481 = 8739582
149 + 8739433 = 8739582
151 + 8739431 = 8739582
191 + 8739391 = 8739582
193 + 8739389 = 8739582

Showing the first eight; more decompositions exist.
