Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55312, here are decompositions:

53 + 55259 = 55312
83 + 55229 = 55312
149 + 55163 = 55312
233 + 55079 = 55312
239 + 55073 = 55312
251 + 55061 = 55312
263 + 55049 = 55312
311 + 55001 = 55312

Showing the first eight; more decompositions exist.
