Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64940, here are decompositions:
- 3 + 64937 = 64940
- 13 + 64927 = 64940
- 19 + 64921 = 64940
- 61 + 64879 = 64940
- 157 + 64783 = 64940
- 193 + 64747 = 64940
- 223 + 64717 = 64940
- 277 + 64663 = 64940
Showing the first eight; more decompositions exist.
