Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757842, here are decompositions:

13 + 8757829 = 8757842
43 + 8757799 = 8757842
73 + 8757769 = 8757842
151 + 8757691 = 8757842
199 + 8757643 = 8757842
271 + 8757571 = 8757842
433 + 8757409 = 8757842
463 + 8757379 = 8757842

Showing the first eight; more decompositions exist.
