Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42750, here are decompositions:
- 7 + 42743 = 42750
- 13 + 42737 = 42750
- 23 + 42727 = 42750
- 31 + 42719 = 42750
- 41 + 42709 = 42750
- 47 + 42703 = 42750
- 53 + 42697 = 42750
- 61 + 42689 = 42750
Showing the first eight; more decompositions exist.
