Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29800, here are decompositions:

11 + 29789 = 29800
41 + 29759 = 29800
47 + 29753 = 29800
59 + 29741 = 29800
83 + 29717 = 29800
131 + 29669 = 29800
137 + 29663 = 29800
167 + 29633 = 29800

Showing the first eight; more decompositions exist.
