Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29440, here are decompositions:

3 + 29437 = 29440
11 + 29429 = 29440
17 + 29423 = 29440
29 + 29411 = 29440
41 + 29399 = 29440
53 + 29387 = 29440
101 + 29339 = 29440
107 + 29333 = 29440

Showing the first eight; more decompositions exist.
