Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126894, here are decompositions:

37 + 126857 = 126894
43 + 126851 = 126894
67 + 126827 = 126894
71 + 126823 = 126894
113 + 126781 = 126894
137 + 126757 = 126894
151 + 126743 = 126894
181 + 126713 = 126894

Showing the first eight; more decompositions exist.
