Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42700, here are decompositions:
- 3 + 42697 = 42700
- 11 + 42689 = 42700
- 17 + 42683 = 42700
- 23 + 42677 = 42700
- 59 + 42641 = 42700
- 89 + 42611 = 42700
- 131 + 42569 = 42700
- 167 + 42533 = 42700
Showing the first eight; more decompositions exist.
