Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127818, here are decompositions:

11 + 127807 = 127818
37 + 127781 = 127818
71 + 127747 = 127818
79 + 127739 = 127818
101 + 127717 = 127818
107 + 127711 = 127818
109 + 127709 = 127818
127 + 127691 = 127818

Showing the first eight; more decompositions exist.
