Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549830, here are decompositions:

13 + 549817 = 549830
79 + 549751 = 549830
97 + 549733 = 549830
139 + 549691 = 549830
163 + 549667 = 549830
181 + 549649 = 549830
223 + 549607 = 549830
241 + 549589 = 549830

Showing the first eight; more decompositions exist.
