Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25430, here are decompositions:

7 + 25423 = 25430
19 + 25411 = 25430
73 + 25357 = 25430
109 + 25321 = 25430
127 + 25303 = 25430
193 + 25237 = 25430
211 + 25219 = 25430
241 + 25189 = 25430

Showing the first eight; more decompositions exist.
