Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549370, here are decompositions:

47 + 549323 = 549370
89 + 549281 = 549370
113 + 549257 = 549370
149 + 549221 = 549370
167 + 549203 = 549370
281 + 549089 = 549370
347 + 549023 = 549370
359 + 549011 = 549370

Showing the first eight; more decompositions exist.
