Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42756, here are decompositions:
- 5 + 42751 = 42756
- 13 + 42743 = 42756
- 19 + 42737 = 42756
- 29 + 42727 = 42756
- 37 + 42719 = 42756
- 47 + 42709 = 42756
- 53 + 42703 = 42756
- 59 + 42697 = 42756
Showing the first eight; more decompositions exist.
