Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556844, here are decompositions:

3 + 556841 = 556844
103 + 556741 = 556844
151 + 556693 = 556844
157 + 556687 = 556844
193 + 556651 = 556844
271 + 556573 = 556844
307 + 556537 = 556844
331 + 556513 = 556844

Showing the first eight; more decompositions exist.
