Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542390, here are decompositions:

19 + 542371 = 542390
67 + 542323 = 542390
97 + 542293 = 542390
109 + 542281 = 542390
127 + 542263 = 542390
139 + 542251 = 542390
193 + 542197 = 542390
223 + 542167 = 542390

Showing the first eight; more decompositions exist.
