Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556226, here are decompositions:

7 + 556219 = 556226
67 + 556159 = 556226
103 + 556123 = 556226
157 + 556069 = 556226
199 + 556027 = 556226
373 + 555853 = 556226
397 + 555829 = 556226
487 + 555739 = 556226

Showing the first eight; more decompositions exist.
