Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73178, here are decompositions:

37 + 73141 = 73178
139 + 73039 = 73178
181 + 72997 = 73178
229 + 72949 = 73178
241 + 72937 = 73178
271 + 72907 = 73178
277 + 72901 = 73178
307 + 72871 = 73178

Showing the first eight; more decompositions exist.
