Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555788, here are decompositions:

97 + 555691 = 555788
127 + 555661 = 555788
151 + 555637 = 555788
199 + 555589 = 555788
349 + 555439 = 555788
367 + 555421 = 555788
397 + 555391 = 555788
439 + 555349 = 555788

Showing the first eight; more decompositions exist.
