Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25378, here are decompositions:
- 5 + 25373 = 25378
- 11 + 25367 = 25378
- 29 + 25349 = 25378
- 71 + 25307 = 25378
- 131 + 25247 = 25378
- 149 + 25229 = 25378
- 251 + 25127 = 25378
- 257 + 25121 = 25378
Showing the first eight; more decompositions exist.
