Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72426, here are decompositions:

5 + 72421 = 72426
43 + 72383 = 72426
47 + 72379 = 72426
59 + 72367 = 72426
73 + 72353 = 72426
89 + 72337 = 72426
113 + 72313 = 72426
139 + 72287 = 72426

Showing the first eight; more decompositions exist.
