Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555658, here are decompositions:

101 + 555557 = 555658
137 + 555521 = 555658
167 + 555491 = 555658
197 + 555461 = 555658
239 + 555419 = 555658
401 + 555257 = 555658
449 + 555209 = 555658
491 + 555167 = 555658

Showing the first eight; more decompositions exist.
