Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549130, here are decompositions:

41 + 549089 = 549130
59 + 549071 = 549130
107 + 549023 = 549130
167 + 548963 = 549130
173 + 548957 = 549130
227 + 548903 = 549130
233 + 548897 = 549130
269 + 548861 = 549130

Showing the first eight; more decompositions exist.
