Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181084, here are decompositions:

3 + 181081 = 181084
23 + 181061 = 181084
53 + 181031 = 181084
83 + 181001 = 181084
311 + 180773 = 181084
353 + 180731 = 181084
383 + 180701 = 181084
461 + 180623 = 181084

Showing the first eight; more decompositions exist.
