Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2438, here are decompositions:

61 + 2377 = 2438
67 + 2371 = 2438
97 + 2341 = 2438
127 + 2311 = 2438
151 + 2287 = 2438
157 + 2281 = 2438
199 + 2239 = 2438
277 + 2161 = 2438

Showing the first eight; more decompositions exist.
