Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549158, here are decompositions:

19 + 549139 = 549158
37 + 549121 = 549158
61 + 549097 = 549158
67 + 549091 = 549158
139 + 549019 = 549158
157 + 549001 = 549158
307 + 548851 = 549158
331 + 548827 = 549158

Showing the first eight; more decompositions exist.
