Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71878, here are decompositions:

11 + 71867 = 71878
17 + 71861 = 71878
29 + 71849 = 71878
41 + 71837 = 71878
71 + 71807 = 71878
89 + 71789 = 71878
101 + 71777 = 71878
137 + 71741 = 71878

Showing the first eight; more decompositions exist.
