Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73190, here are decompositions:

127 + 73063 = 73190
151 + 73039 = 73190
181 + 73009 = 73190
193 + 72997 = 73190
241 + 72949 = 73190
283 + 72907 = 73190
307 + 72883 = 73190
331 + 72859 = 73190

Showing the first eight; more decompositions exist.
