Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40178, here are decompositions:

67 + 40111 = 40178
79 + 40099 = 40178
139 + 40039 = 40178
199 + 39979 = 40178
241 + 39937 = 40178
277 + 39901 = 40178
331 + 39847 = 40178
337 + 39841 = 40178

Showing the first eight; more decompositions exist.
