Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181046, here are decompositions:

7 + 181039 = 181046
43 + 181003 = 181046
97 + 180949 = 181046
139 + 180907 = 181046
163 + 180883 = 181046
199 + 180847 = 181046
367 + 180679 = 181046
379 + 180667 = 181046

Showing the first eight; more decompositions exist.
