Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542370, here are decompositions:

47 + 542323 = 542370
71 + 542299 = 542370
89 + 542281 = 542370
107 + 542263 = 542370
109 + 542261 = 542370
151 + 542219 = 542370
163 + 542207 = 542370
173 + 542197 = 542370

Showing the first eight; more decompositions exist.
