Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86040, here are decompositions:

11 + 86029 = 86040
13 + 86027 = 86040
23 + 86017 = 86040
29 + 86011 = 86040
41 + 85999 = 86040
107 + 85933 = 86040
109 + 85931 = 86040
131 + 85909 = 86040

Showing the first eight; more decompositions exist.
