Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555778, here are decompositions:

11 + 555767 = 555778
17 + 555761 = 555778
71 + 555707 = 555778
101 + 555677 = 555778
107 + 555671 = 555778
257 + 555521 = 555778
317 + 555461 = 555778
359 + 555419 = 555778

Showing the first eight; more decompositions exist.
