Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72678, here are decompositions:

5 + 72673 = 72678
7 + 72671 = 72678
17 + 72661 = 72678
29 + 72649 = 72678
31 + 72647 = 72678
61 + 72617 = 72678
101 + 72577 = 72678
127 + 72551 = 72678

Showing the first eight; more decompositions exist.
