Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555628, here are decompositions:

71 + 555557 = 555628
107 + 555521 = 555628
137 + 555491 = 555628
167 + 555461 = 555628
419 + 555209 = 555628
461 + 555167 = 555628
509 + 555119 = 555628
587 + 555041 = 555628

Showing the first eight; more decompositions exist.
