Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64880, here are decompositions:
- 3 + 64877 = 64880
- 31 + 64849 = 64880
- 97 + 64783 = 64880
- 163 + 64717 = 64880
- 271 + 64609 = 64880
- 313 + 64567 = 64880
- 367 + 64513 = 64880
- 397 + 64483 = 64880
Showing the first eight; more decompositions exist.
