Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25730, here are decompositions:

13 + 25717 = 25730
37 + 25693 = 25730
73 + 25657 = 25730
97 + 25633 = 25730
109 + 25621 = 25730
127 + 25603 = 25730
151 + 25579 = 25730
193 + 25537 = 25730

Showing the first eight; more decompositions exist.
