Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542784, here are decompositions:

13 + 542771 = 542784
23 + 542761 = 542784
37 + 542747 = 542784
61 + 542723 = 542784
71 + 542713 = 542784
97 + 542687 = 542784
101 + 542683 = 542784
181 + 542603 = 542784

Showing the first eight; more decompositions exist.
