Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72662, here are decompositions:

13 + 72649 = 72662
19 + 72643 = 72662
103 + 72559 = 72662
181 + 72481 = 72662
193 + 72469 = 72662
241 + 72421 = 72662
283 + 72379 = 72662
349 + 72313 = 72662

Showing the first eight; more decompositions exist.
