Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55378, here are decompositions:

5 + 55373 = 55378
41 + 55337 = 55378
47 + 55331 = 55378
149 + 55229 = 55378
251 + 55127 = 55378
269 + 55109 = 55378
317 + 55061 = 55378
419 + 54959 = 55378

Showing the first eight; more decompositions exist.
