Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55318, here are decompositions:

5 + 55313 = 55318
59 + 55259 = 55318
89 + 55229 = 55318
101 + 55217 = 55318
191 + 55127 = 55318
239 + 55079 = 55318
257 + 55061 = 55318
269 + 55049 = 55318

Showing the first eight; more decompositions exist.
