Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29872, here are decompositions:

5 + 29867 = 29872
53 + 29819 = 29872
83 + 29789 = 29872
113 + 29759 = 29872
131 + 29741 = 29872
149 + 29723 = 29872
239 + 29633 = 29872
389 + 29483 = 29872

Showing the first eight; more decompositions exist.
