Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701842, here are decompositions:

29 + 8701813 = 8701842
31 + 8701811 = 8701842
53 + 8701789 = 8701842
101 + 8701741 = 8701842
113 + 8701729 = 8701842
139 + 8701703 = 8701842
199 + 8701643 = 8701842
211 + 8701631 = 8701842

Showing the first eight; more decompositions exist.
