Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542250, here are decompositions:

13 + 542237 = 542250
31 + 542219 = 542250
43 + 542207 = 542250
53 + 542197 = 542250
61 + 542189 = 542250
67 + 542183 = 542250
83 + 542167 = 542250
97 + 542153 = 542250

Showing the first eight; more decompositions exist.
