Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725542, here are decompositions:

11 + 8725531 = 8725542
19 + 8725523 = 8725542
31 + 8725511 = 8725542
43 + 8725499 = 8725542
53 + 8725489 = 8725542
61 + 8725481 = 8725542
79 + 8725463 = 8725542
83 + 8725459 = 8725542

Showing the first eight; more decompositions exist.
