Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8042, here are decompositions:

3 + 8039 = 8042
31 + 8011 = 8042
79 + 7963 = 8042
109 + 7933 = 8042
163 + 7879 = 8042
283 + 7759 = 8042
373 + 7669 = 8042
421 + 7621 = 8042

Showing the first eight; more decompositions exist.
