Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542502, here are decompositions:

5 + 542497 = 542502
13 + 542489 = 542502
19 + 542483 = 542502
41 + 542461 = 542502
61 + 542441 = 542502
101 + 542401 = 542502
131 + 542371 = 542502
179 + 542323 = 542502

Showing the first eight; more decompositions exist.
