Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555722, here are decompositions:

31 + 555691 = 555722
61 + 555661 = 555722
199 + 555523 = 555722
283 + 555439 = 555722
331 + 555391 = 555722
373 + 555349 = 555722
421 + 555301 = 555722
613 + 555109 = 555722

Showing the first eight; more decompositions exist.
