Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42836, here are decompositions:

7 + 42829 = 42836
43 + 42793 = 42836
109 + 42727 = 42836
127 + 42709 = 42836
139 + 42697 = 42836
193 + 42643 = 42836
337 + 42499 = 42836
349 + 42487 = 42836

Showing the first eight; more decompositions exist.
