Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47742, here are decompositions:
- 5 + 47737 = 47742
- 29 + 47713 = 47742
- 31 + 47711 = 47742
- 41 + 47701 = 47742
- 43 + 47699 = 47742
- 61 + 47681 = 47742
- 83 + 47659 = 47742
- 89 + 47653 = 47742
Showing the first eight; more decompositions exist.
