Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556042, here are decompositions:

5 + 556037 = 556042
89 + 555953 = 556042
101 + 555941 = 556042
281 + 555761 = 556042
359 + 555683 = 556042
449 + 555593 = 556042
521 + 555521 = 556042
659 + 555383 = 556042

Showing the first eight; more decompositions exist.
