Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715842, here are decompositions:

73 + 8715769 = 8715842
139 + 8715703 = 8715842
193 + 8715649 = 8715842
241 + 8715601 = 8715842
283 + 8715559 = 8715842
433 + 8715409 = 8715842
439 + 8715403 = 8715842
661 + 8715181 = 8715842

Showing the first eight; more decompositions exist.
