Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2378, here are decompositions:

7 + 2371 = 2378
31 + 2347 = 2378
37 + 2341 = 2378
67 + 2311 = 2378
97 + 2281 = 2378
109 + 2269 = 2378
127 + 2251 = 2378
139 + 2239 = 2378

Showing the first eight; more decompositions exist.
