Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558142, here are decompositions:

3 + 558139 = 558142
29 + 558113 = 558142
59 + 558083 = 558142
89 + 558053 = 558142
113 + 558029 = 558142
239 + 557903 = 558142
251 + 557891 = 558142
281 + 557861 = 558142

Showing the first eight; more decompositions exist.
