Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555626, here are decompositions:

37 + 555589 = 555626
103 + 555523 = 555626
139 + 555487 = 555626
277 + 555349 = 555626
349 + 555277 = 555626
373 + 555253 = 555626
727 + 554899 = 555626
733 + 554893 = 555626

Showing the first eight; more decompositions exist.
