Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555844, here are decompositions:

17 + 555827 = 555844
83 + 555761 = 555844
101 + 555743 = 555844
137 + 555707 = 555844
167 + 555677 = 555844
173 + 555671 = 555844
251 + 555593 = 555844
353 + 555491 = 555844

Showing the first eight; more decompositions exist.
