Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181076, here are decompositions:

13 + 181063 = 181076
37 + 181039 = 181076
73 + 181003 = 181076
127 + 180949 = 181076
193 + 180883 = 181076
229 + 180847 = 181076
277 + 180799 = 181076
283 + 180793 = 181076

Showing the first eight; more decompositions exist.
