Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64844, here are decompositions:
- 61 + 64783 = 64844
- 97 + 64747 = 64844
- 127 + 64717 = 64844
- 151 + 64693 = 64844
- 181 + 64663 = 64844
- 211 + 64633 = 64844
- 223 + 64621 = 64844
- 277 + 64567 = 64844
Showing the first eight; more decompositions exist.
