Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556982, here are decompositions:

43 + 556939 = 556982
163 + 556819 = 556982
193 + 556789 = 556982
229 + 556753 = 556982
241 + 556741 = 556982
331 + 556651 = 556982
373 + 556609 = 556982
409 + 556573 = 556982

Showing the first eight; more decompositions exist.
