Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25748, here are decompositions:
- 7 + 25741 = 25748
- 31 + 25717 = 25748
- 109 + 25639 = 25748
- 127 + 25621 = 25748
- 139 + 25609 = 25748
- 211 + 25537 = 25748
- 277 + 25471 = 25748
- 337 + 25411 = 25748
Showing the first eight; more decompositions exist.
