Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542380, here are decompositions:

173 + 542207 = 542380
191 + 542189 = 542380
197 + 542183 = 542380
227 + 542153 = 542380
239 + 542141 = 542380
257 + 542123 = 542380
263 + 542117 = 542380
269 + 542111 = 542380

Showing the first eight; more decompositions exist.
