Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555958, here are decompositions:

5 + 555953 = 555958
17 + 555941 = 555958
101 + 555857 = 555958
131 + 555827 = 555958
191 + 555767 = 555958
197 + 555761 = 555958
251 + 555707 = 555958
281 + 555677 = 555958

Showing the first eight; more decompositions exist.
