Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001392, here are decompositions:

3 + 1001389 = 1001392
5 + 1001387 = 1001392
11 + 1001381 = 1001392
23 + 1001369 = 1001392
71 + 1001321 = 1001392
89 + 1001303 = 1001392
101 + 1001291 = 1001392
113 + 1001279 = 1001392

Showing the first eight; more decompositions exist.
