Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713842, here are decompositions:

19 + 8713823 = 8713842
29 + 8713813 = 8713842
31 + 8713811 = 8713842
61 + 8713781 = 8713842
79 + 8713763 = 8713842
149 + 8713693 = 8713842
199 + 8713643 = 8713842
211 + 8713631 = 8713842

Showing the first eight; more decompositions exist.
