Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72378, here are decompositions:

11 + 72367 = 72378
37 + 72341 = 72378
41 + 72337 = 72378
71 + 72307 = 72378
101 + 72277 = 72378
107 + 72271 = 72378
109 + 72269 = 72378
127 + 72251 = 72378

Showing the first eight; more decompositions exist.
