Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185822, here are decompositions:

3 + 185819 = 185822
73 + 185749 = 185822
139 + 185683 = 185822
181 + 185641 = 185822
223 + 185599 = 185822
229 + 185593 = 185822
271 + 185551 = 185822
283 + 185539 = 185822

Showing the first eight; more decompositions exist.
