Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555818, here are decompositions:

79 + 555739 = 555818
127 + 555691 = 555818
157 + 555661 = 555818
181 + 555637 = 555818
229 + 555589 = 555818
331 + 555487 = 555818
379 + 555439 = 555818
397 + 555421 = 555818

Showing the first eight; more decompositions exist.
