Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42744, here are decompositions:
- 7 + 42737 = 42744
- 17 + 42727 = 42744
- 41 + 42703 = 42744
- 43 + 42701 = 42744
- 47 + 42697 = 42744
- 61 + 42683 = 42744
- 67 + 42677 = 42744
- 101 + 42643 = 42744
Showing the first eight; more decompositions exist.
