Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85722, here are decompositions:

5 + 85717 = 85722
11 + 85711 = 85722
19 + 85703 = 85722
31 + 85691 = 85722
53 + 85669 = 85722
61 + 85661 = 85722
79 + 85643 = 85722
83 + 85639 = 85722

Showing the first eight; more decompositions exist.
