Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47442, here are decompositions:

11 + 47431 = 47442
23 + 47419 = 47442
53 + 47389 = 47442
61 + 47381 = 47442
79 + 47363 = 47442
89 + 47353 = 47442
103 + 47339 = 47442
139 + 47303 = 47442

Showing the first eight; more decompositions exist.
