Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556784, here are decompositions:

3 + 556781 = 556784
31 + 556753 = 556784
43 + 556741 = 556784
61 + 556723 = 556784
97 + 556687 = 556784
157 + 556627 = 556784
211 + 556573 = 556784
271 + 556513 = 556784

Showing the first eight; more decompositions exist.
