Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29810, here are decompositions:

7 + 29803 = 29810
127 + 29683 = 29810
139 + 29671 = 29810
181 + 29629 = 29810
199 + 29611 = 29810
211 + 29599 = 29810
223 + 29587 = 29810
229 + 29581 = 29810

Showing the first eight; more decompositions exist.
