Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555142, here are decompositions:

23 + 555119 = 555142
59 + 555083 = 555142
89 + 555053 = 555142
101 + 555041 = 555142
113 + 555029 = 555142
173 + 554969 = 555142
191 + 554951 = 555142
251 + 554891 = 555142

Showing the first eight; more decompositions exist.
