Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542660, here are decompositions:

61 + 542599 = 542660
73 + 542587 = 542660
103 + 542557 = 542660
109 + 542551 = 542660
127 + 542533 = 542660
163 + 542497 = 542660
193 + 542467 = 542660
199 + 542461 = 542660

Showing the first eight; more decompositions exist.
