Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557784, here are decompositions:

5 + 557779 = 557784
23 + 557761 = 557784
37 + 557747 = 557784
41 + 557743 = 557784
43 + 557741 = 557784
53 + 557731 = 557784
67 + 557717 = 557784
113 + 557671 = 557784

Showing the first eight; more decompositions exist.
