Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72444, here are decompositions:

13 + 72431 = 72444
23 + 72421 = 72444
61 + 72383 = 72444
103 + 72341 = 72444
107 + 72337 = 72444
131 + 72313 = 72444
137 + 72307 = 72444
157 + 72287 = 72444

Showing the first eight; more decompositions exist.
