Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572742, here are decompositions:

31 + 572711 = 572742
43 + 572699 = 572742
59 + 572683 = 572742
83 + 572659 = 572742
89 + 572653 = 572742
103 + 572639 = 572742
109 + 572633 = 572742
113 + 572629 = 572742

Showing the first eight; more decompositions exist.
