Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30836, here are decompositions:

7 + 30829 = 30836
19 + 30817 = 30836
73 + 30763 = 30836
79 + 30757 = 30836
109 + 30727 = 30836
139 + 30697 = 30836
193 + 30643 = 30836
199 + 30637 = 30836

Showing the first eight; more decompositions exist.
