Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542662, here are decompositions:

59 + 542603 = 542662
83 + 542579 = 542662
173 + 542489 = 542662
179 + 542483 = 542662
401 + 542261 = 542662
443 + 542219 = 542662
479 + 542183 = 542662
509 + 542153 = 542662

Showing the first eight; more decompositions exist.
