Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65144, here are decompositions:
- 3 + 65141 = 65144
- 43 + 65101 = 65144
- 73 + 65071 = 65144
- 193 + 64951 = 65144
- 223 + 64921 = 65144
- 397 + 64747 = 65144
- 523 + 64621 = 65144
- 577 + 64567 = 65144
Showing the first eight; more decompositions exist.
