Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719542, here are decompositions:

23 + 8719519 = 8719542
59 + 8719483 = 8719542
101 + 8719441 = 8719542
151 + 8719391 = 8719542
163 + 8719379 = 8719542
193 + 8719349 = 8719542
239 + 8719303 = 8719542
241 + 8719301 = 8719542

Showing the first eight; more decompositions exist.
