Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556778, here are decompositions:

37 + 556741 = 556778
127 + 556651 = 556778
139 + 556639 = 556778
151 + 556627 = 556778
199 + 556579 = 556778
241 + 556537 = 556778
337 + 556441 = 556778
379 + 556399 = 556778

Showing the first eight; more decompositions exist.
