Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42800, here are decompositions:
- 3 + 42797 = 42800
- 7 + 42793 = 42800
- 13 + 42787 = 42800
- 73 + 42727 = 42800
- 97 + 42703 = 42800
- 103 + 42697 = 42800
- 151 + 42649 = 42800
- 157 + 42643 = 42800
Showing the first eight; more decompositions exist.
