Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184722, here are decompositions:

11 + 184711 = 184722
19 + 184703 = 184722
29 + 184693 = 184722
53 + 184669 = 184722
71 + 184651 = 184722
73 + 184649 = 184722
89 + 184633 = 184722
113 + 184609 = 184722

Showing the first eight; more decompositions exist.
