Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181676, here are decompositions:

7 + 181669 = 181676
37 + 181639 = 181676
67 + 181609 = 181676
73 + 181603 = 181676
127 + 181549 = 181676
139 + 181537 = 181676
163 + 181513 = 181676
277 + 181399 = 181676

Showing the first eight; more decompositions exist.
