Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181044, here are decompositions:

5 + 181039 = 181044
13 + 181031 = 181044
41 + 181003 = 181044
43 + 181001 = 181044
137 + 180907 = 181044
173 + 180871 = 181044
197 + 180847 = 181044
233 + 180811 = 181044

Showing the first eight; more decompositions exist.
