Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542618, here are decompositions:

19 + 542599 = 542618
31 + 542587 = 542618
61 + 542557 = 542618
67 + 542551 = 542618
79 + 542539 = 542618
151 + 542467 = 542618
157 + 542461 = 542618
337 + 542281 = 542618

Showing the first eight; more decompositions exist.
