Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184940, here are decompositions:

37 + 184903 = 184940
61 + 184879 = 184940
97 + 184843 = 184940
103 + 184837 = 184940
109 + 184831 = 184940
163 + 184777 = 184940
229 + 184711 = 184940
271 + 184669 = 184940

Showing the first eight; more decompositions exist.
