Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29790, here are decompositions:

29 + 29761 = 29790
31 + 29759 = 29790
37 + 29753 = 29790
67 + 29723 = 29790
73 + 29717 = 29790
107 + 29683 = 29790
127 + 29663 = 29790
149 + 29641 = 29790

Showing the first eight; more decompositions exist.
