Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178554, here are decompositions:

17 + 178537 = 178554
23 + 178531 = 178554
41 + 178513 = 178554
53 + 178501 = 178554
67 + 178487 = 178554
73 + 178481 = 178554
107 + 178447 = 178554
113 + 178441 = 178554

Showing the first eight; more decompositions exist.
