Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715542, here are decompositions:

19 + 8715523 = 8715542
139 + 8715403 = 8715542
181 + 8715361 = 8715542
193 + 8715349 = 8715542
349 + 8715193 = 8715542
439 + 8715103 = 8715542
463 + 8715079 = 8715542
523 + 8715019 = 8715542

Showing the first eight; more decompositions exist.
