Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29918, here are decompositions:

37 + 29881 = 29918
67 + 29851 = 29918
157 + 29761 = 29918
277 + 29641 = 29918
307 + 29611 = 29918
331 + 29587 = 29918
337 + 29581 = 29918
349 + 29569 = 29918

Showing the first eight; more decompositions exist.
