Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556688, here are decompositions:

37 + 556651 = 556688
61 + 556627 = 556688
79 + 556609 = 556688
109 + 556579 = 556688
151 + 556537 = 556688
211 + 556477 = 556688
229 + 556459 = 556688
337 + 556351 = 556688

Showing the first eight; more decompositions exist.
