Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25972, here are decompositions:
- 3 + 25969 = 25972
- 29 + 25943 = 25972
- 41 + 25931 = 25972
- 53 + 25919 = 25972
- 59 + 25913 = 25972
- 83 + 25889 = 25972
- 131 + 25841 = 25972
- 173 + 25799 = 25972
Showing the first eight; more decompositions exist.
