Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72442, here are decompositions:

11 + 72431 = 72442
59 + 72383 = 72442
89 + 72353 = 72442
101 + 72341 = 72442
173 + 72269 = 72442
191 + 72251 = 72442
269 + 72173 = 72442
281 + 72161 = 72442

Showing the first eight; more decompositions exist.
