Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556520, here are decompositions:

7 + 556513 = 556520
37 + 556483 = 556520
43 + 556477 = 556520
61 + 556459 = 556520
79 + 556441 = 556520
193 + 556327 = 556520
199 + 556321 = 556520
241 + 556279 = 556520

Showing the first eight; more decompositions exist.
