Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72462, here are decompositions:

31 + 72431 = 72462
41 + 72421 = 72462
79 + 72383 = 72462
83 + 72379 = 72462
109 + 72353 = 72462
149 + 72313 = 72462
191 + 72271 = 72462
193 + 72269 = 72462

Showing the first eight; more decompositions exist.
