Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542644, here are decompositions:

41 + 542603 = 542644
107 + 542537 = 542644
197 + 542447 = 542644
383 + 542261 = 542644
461 + 542183 = 542644
491 + 542153 = 542644
503 + 542141 = 542644
521 + 542123 = 542644

Showing the first eight; more decompositions exist.
