Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549142, here are decompositions:

3 + 549139 = 549142
53 + 549089 = 549142
71 + 549071 = 549142
131 + 549011 = 549142
179 + 548963 = 549142
233 + 548909 = 549142
239 + 548903 = 549142
281 + 548861 = 549142

Showing the first eight; more decompositions exist.
