Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709542, here are decompositions:

73 + 8709469 = 8709542
181 + 8709361 = 8709542
229 + 8709313 = 8709542
241 + 8709301 = 8709542
271 + 8709271 = 8709542
313 + 8709229 = 8709542
409 + 8709133 = 8709542
421 + 8709121 = 8709542

Showing the first eight; more decompositions exist.
