Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527642, here are decompositions:

19 + 527623 = 527642
43 + 527599 = 527642
61 + 527581 = 527642
79 + 527563 = 527642
109 + 527533 = 527642
223 + 527419 = 527642
433 + 527209 = 527642
439 + 527203 = 527642

Showing the first eight; more decompositions exist.
