Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87444, here are decompositions:

11 + 87433 = 87444
17 + 87427 = 87444
23 + 87421 = 87444
37 + 87407 = 87444
41 + 87403 = 87444
61 + 87383 = 87444
107 + 87337 = 87444
127 + 87317 = 87444

Showing the first eight; more decompositions exist.
