Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555090, here are decompositions:

7 + 555083 = 555090
13 + 555077 = 555090
17 + 555073 = 555090
37 + 555053 = 555090
47 + 555043 = 555090
61 + 555029 = 555090
113 + 554977 = 555090
131 + 554959 = 555090

Showing the first eight; more decompositions exist.
