Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29390, here are decompositions:

3 + 29387 = 29390
7 + 29383 = 29390
43 + 29347 = 29390
79 + 29311 = 29390
103 + 29287 = 29390
139 + 29251 = 29390
181 + 29209 = 29390
199 + 29191 = 29390

Showing the first eight; more decompositions exist.
