Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56840, here are decompositions:
- 13 + 56827 = 56840
- 19 + 56821 = 56840
- 31 + 56809 = 56840
- 61 + 56779 = 56840
- 67 + 56773 = 56840
- 73 + 56767 = 56840
- 103 + 56737 = 56840
- 109 + 56731 = 56840
Showing the first eight; more decompositions exist.
