Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89742, here are decompositions:
- 53 + 89689 = 89742
- 61 + 89681 = 89742
- 71 + 89671 = 89742
- 73 + 89669 = 89742
- 83 + 89659 = 89742
- 89 + 89653 = 89742
- 109 + 89633 = 89742
- 131 + 89611 = 89742
Showing the first eight; more decompositions exist.
