Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542398, here are decompositions:

137 + 542261 = 542398
179 + 542219 = 542398
191 + 542207 = 542398
257 + 542141 = 542398
281 + 542117 = 542398
317 + 542081 = 542398
431 + 541967 = 542398
509 + 541889 = 542398

Showing the first eight; more decompositions exist.
