Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89472, here are decompositions:

13 + 89459 = 89472
23 + 89449 = 89472
29 + 89443 = 89472
41 + 89431 = 89472
59 + 89413 = 89472
73 + 89399 = 89472
79 + 89393 = 89472
101 + 89371 = 89472

Showing the first eight; more decompositions exist.
