Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25180, here are decompositions:

11 + 25169 = 25180
17 + 25163 = 25180
53 + 25127 = 25180
59 + 25121 = 25180
83 + 25097 = 25180
107 + 25073 = 25180
149 + 25031 = 25180
167 + 25013 = 25180

Showing the first eight; more decompositions exist.
