Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86722, here are decompositions:

3 + 86719 = 86722
11 + 86711 = 86722
29 + 86693 = 86722
149 + 86573 = 86722
191 + 86531 = 86722
269 + 86453 = 86722
281 + 86441 = 86722
353 + 86369 = 86722

Showing the first eight; more decompositions exist.
