Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89442, here are decompositions:

11 + 89431 = 89442
29 + 89413 = 89442
43 + 89399 = 89442
61 + 89381 = 89442
71 + 89371 = 89442
79 + 89363 = 89442
113 + 89329 = 89442
139 + 89303 = 89442

Showing the first eight; more decompositions exist.
