Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25722, here are decompositions:

5 + 25717 = 25722
19 + 25703 = 25722
29 + 25693 = 25722
43 + 25679 = 25722
79 + 25643 = 25722
83 + 25639 = 25722
89 + 25633 = 25722
101 + 25621 = 25722

Showing the first eight; more decompositions exist.
