Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556246, here are decompositions:

3 + 556243 = 556246
17 + 556229 = 556246
179 + 556067 = 556246
239 + 556007 = 556246
293 + 555953 = 556246
389 + 555857 = 556246
419 + 555827 = 556246
479 + 555767 = 556246

Showing the first eight; more decompositions exist.
