Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542658, here are decompositions:

59 + 542599 = 542658
71 + 542587 = 542658
79 + 542579 = 542658
101 + 542557 = 542658
107 + 542551 = 542658
139 + 542519 = 542658
191 + 542467 = 542658
197 + 542461 = 542658

Showing the first eight; more decompositions exist.
