Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102378, here are decompositions:

11 + 102367 = 102378
19 + 102359 = 102378
41 + 102337 = 102378
61 + 102317 = 102378
79 + 102299 = 102378
127 + 102251 = 102378
137 + 102241 = 102378
149 + 102229 = 102378

Showing the first eight; more decompositions exist.
