Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42772, here are decompositions:

5 + 42767 = 42772
29 + 42743 = 42772
53 + 42719 = 42772
71 + 42701 = 42772
83 + 42689 = 42772
89 + 42683 = 42772
131 + 42641 = 42772
239 + 42533 = 42772

Showing the first eight; more decompositions exist.
