Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542318, here are decompositions:

19 + 542299 = 542318
37 + 542281 = 542318
67 + 542251 = 542318
151 + 542167 = 542318
199 + 542119 = 542318
331 + 541987 = 542318
367 + 541951 = 542318
487 + 541831 = 542318

Showing the first eight; more decompositions exist.
