Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25140, here are decompositions:

13 + 25127 = 25140
19 + 25121 = 25140
23 + 25117 = 25140
29 + 25111 = 25140
43 + 25097 = 25140
53 + 25087 = 25140
67 + 25073 = 25140
83 + 25057 = 25140

Showing the first eight; more decompositions exist.
